KERN EW 6200-2NM Precision Balance, 6,200 g / 0.01 g, tuning fork principle
KERN EW 6200-2NM: The indestructible classic with tuning fork technology The KERN EW 6200-2NM is more than just a balance – it is synonymous with long-lasting precision. As part of the legendary EW-N series, this model utilises the high-quality tuning fork measuring principle. Unlike scales with force compensation or strain gauges, which are often sensitive to temperature fluctuations or require long warm-up times, the EW 6200-2NM is ready to use straight away. Switch it on and start weighing – no waiting required. With a weighing range of 6,200 g (6.2 kg) and an extremely fine readability of 0.01 g , it bridges the gap between laboratory analysis and robust industrial scales. Why tuning-fork technology? No warm-up time: Whilst other precision balances need to be plugged in for up to 2 hours to reach thermal stability, the EW 6200-2NM delivers stable readings immediately after being switched on. Ideal for mobile use or laboratories where the balance is not in operation 24/7. Robustness: The system is extremely resistant to mechanical stress. The tuning fork system withstands shocks and overloads far better than electromagnetic force-compensation cells. Long-term stability: The calibration remains stable over long periods, minimising maintenance requirements. Features for everyday professional use Capacity indicator: A gradually lighting-up strip on the display shows you how much of the weighing range is still available. This prevents accidental overloading during weighing. Piece counting: Thanks to the high resolution, even very light parts can be counted precisely. The reference count can be selected (10, 30, 50, 100). Percentage calculation: Ideal for recipes. You can define the weight of a container as 100% and read off differences directly as a percentage. Data interface: The standard RS-232 interface allows connection to a PC or printer (GLP logging possible with a compatible KERN printer). Calibration and design The KERN EW 6200-2NM is calibrated externally. This means you use a defined test weight (available separately) to regularly check and adjust the accuracy (CAL programme). The large stainless steel weighing plate (180 x 160 mm) offers sufficient space for beakers or flasks and is easy to clean. A spirit level and levelling screws for precise levelling are supplied as standard. Technical data Model: EW 6200-2NM Weighing range (max): 6,200 g Readability (d): 0.01 g Reproducibility: 0.01 g Linearity: ± 0.03 g Settling time: 3 s Measuring system: Tuning fork Weighing plate: 180 x 160 mm (stainless steel) Calibration: External (Recommended calibration weight: 5 kg, Class E2) Interface: RS-232 Display: LCD, digit height 17 mm Housing dimensions (W x D x H): 182 x 235 x 75 mm Net weight: approx. 2.9 kg Permissible ambient temperature: +10 °C to +30 °C Contents 1 x KERN EW 6200-2NM 1 x mains adaptor 1 x safety cover (over keyboard and housing) 1 x user manual Individual requirements & accessories To ensure the long-term accuracy of this balance, we recommend the appropriate test weight (Class E2 or F1).

KERN DLB 160-3A, moisture analyser, halogen, 160 g / 0.001 g
Thermodynamic Halogen Transmission and Thermogravimetry In analytical materials testing, determining the absolute water or solvent content requires a highly precise integration of thermodynamics and mass metrology. The KERN DLB 160-3A operates according to the process engineering principle of thermogravimetry. Thermal energy is supplied to the matrix via a solid, ring-shaped 400-watt halogen quartz glass emitter. This infrared emitter transfers the radiant energy directly into the molecular structure of the sample with extremely low losses, generating steep, reproducible heating rates up to 160 °C. In contrast to convective drying processes, this system hydrodynamically drives out the volatile phases (moisture) via direct infrared coupling in a fraction of the usual process time, whilst the escaping thermodynamic vectors (vapours) are vented via the housing design. Metrological cybernetics and gravimetric integration The fundamental analytical architecture is the real-time metrological integration of mass loss. Whilst the halogen unit dries the matrix thermodynamically, the integrated high-precision load cell continuously records the decreasing weight with an absolute physical resolution of 0.001 g (1 mg) at a maximum load of 160 g. The system’s cybernetic algorithm correlates this gravimetric drift in real time with the parameters of time and temperature. As soon as the weight loss per unit of time (Δm/Δt) falls below a defined metrological threshold criterion, the system autonomously terminates the thermal emission cycle. The LCD display then shows the absolute moisture content with an analytical precision of 0.01%. System stability and GLP-compliant data logging The reproducibility of thermogravimetric assays requires uncompromising shielding against external disturbances. The structural chassis of the DLB 160-3A is designed to absorb mechanical vibrations from the laboratory bench in order to protect the highly sensitive milligram-scale sensor technology from resonance-induced failures. The system interface integrates all process parameters (heating profiles, stop criteria) into a high-contrast display. For validation in accredited laboratories, the RS-232 data interface transmits the complete drying reports (including initial weight, final weight, percentage moisture content and timestamps) in full to external GLP/GMP-compliant printers or to the Laboratory Information Management System (LIMS). Technical details Thermodynamics & Heating Technology Heating technology: Halogen quartz glass heater (ring-shaped) Heating power: 400 W Thermodynamic operating range: 35 °C to 160 °C Temperature increment (resolution): 1 °C Heating profiles: Standard drying Metrology & Gravimetry Maximum weighing capacity (Max): 160 g Gravimetric readability (d): 0.001 g (1 mg) Reproducibility (10 g sample): 0.05 % Moisture readability (per cent): 0.01% Measuring principle: Strain gauge (SG) Settling time: approx. 3 s System infrastructure & dimensions Sample dish diameter: 90 mm System dimensions (W x D x H): 215 x 345 x 235 mm Machine weight: approx. 4.7 kg Display: High-contrast LCD with digit height of 17 mm Housing material: Chemical-resistant high-performance plastic Safety & Electrical Permissible ambient temperature range: 5 °C to 35 °C Permissible relative humidity: max. 80% (non-condensing) Input voltage: 230 V / 50 Hz Data interface: RS-232 (for printer and PC connection) Contents of delivery 1 x KERN DLB 160-3A moisture analyser 10 x aluminium sample dishes (Ø 90 mm) 1 x power cable for cooling units Important note: Specific glass fibre filters (to prevent splashing with highly liquid matrices) and external test weights (Class F1) for the metrological recalibration of the gravimetric system are physically essential for GLP-compliant operation and are not included in the scope of delivery. Individual requirements & accessories The DLB 160-3A induces a rapid phase transition (evaporation) via infrared radiation. For samples that tend to form a skin, splash or are highly liquid, the fluid must be distributed by capillary action via a round glass fibre filter; otherwise, the thermodynamic surface will become blocked or the quartz glass will be contaminated by eruptions. As the load cell is subject to thermal fluctuations, it is essential to obtain an external F1 calibration weight (e.g. 100 g) in order to carry out calibration prior to critical measurement series. Consumables such as high-purity, disposable aluminium sample dishes are available via our procurement service to prevent cross-contamination.
KERN DBS 60-3 Halogen Moisture Analyser, 60 g / 0.001 g (0.01 %), graphic display
Precision for demanding quality control: The KERN DBS 60-3 halogen moisture analyser The precise determination of moisture content in raw materials, intermediate products and finished goods is an absolutely business-critical factor in virtually every modern production and laboratory environment. Whether in the food industry to determine the shelf life of cereals and baked goods, in plastics processing to prevent air pockets during injection moulding caused by granules that are too moist, or in pharmaceutical quality control – even the slightest deviations in moisture content can severely compromise the quality of the end product and lead to immense financial losses. It is precisely for these highly sensitive and strictly regulated areas of application that KERN has developed the professional halogen moisture analyser DBS 60-3 (MPN DBS 60-3). This intelligent and high-performance measuring instrument replaces the time-consuming, traditional drying method using a conventional drying oven and provides you with highly precise, reproducible moisture readings within a few minutes, right at your laboratory workstation. Powerful and uniform halogen technology At the technological heart of the KERN DBS 60-3 lies an extremely powerful halogen quartz glass emitter with an output of 400 watts. Compared directly with conventional infrared emitters or metallic heating coils, halogen technology offers the decisive advantage of heat generation with virtually no delay. The target temperature is reached in record time, which significantly shortens the overall duration of the drying process. Furthermore, the sophisticated geometry of the emitter within the enclosed sample chamber ensures absolutely homogeneous and uniform heat distribution across the entire surface of the aluminium sample dish. This reliably prevents so-called ‘hotspots’ (localised overheating), which could lead to undesirable burning or charring on the surface of the sample. The drying temperature can be set via the control panel in fine 1 °C increments across an extremely wide temperature range from 50 °C to a maximum of 200 °C, making the instrument ideally suited to a vast spectrum of different materials. Outstanding resolution for tiny sample quantities The performance of the heating system is complemented by a high-precision load cell. The KERN DBS 60-3 offers a weighing range of up to 60 grams, which is more than sufficient for the vast majority of routine applications in moisture analysis. The real highlight of this model, however, lies in its outstanding readability of 0.001 gram (which corresponds exactly to a moisture content of 0.01 per cent). This extremely fine resolution is essential when working with very valuable, expensive or hard-to-obtain samples, where only very small sample weights (for example, 2 to 5 grams) can be used for analysis. Even with these minimal sample quantities, the balance reliably detects fractions of a milligram of evaporated water and uses this to calculate a mathematically precise, reliable moisture profile. Four intelligent drying profiles for maximum flexibility Not every sample can be dried in the same way. A liquid resin behaves completely differently when exposed to heat than a dry powder or a pasty food sample. To take this into account, the KERN DBS 60-3 is equipped with four different, freely selectable heating profiles. Standard drying heats the sample rapidly to the set temperature and maintains it at a constant level. Rapid drying slightly exceeds the target temperature in the first few minutes to maximise the drying process for very moist samples. Gentle drying, on the other hand, increases the heat very slowly and gently – the perfect choice for temperature-sensitive, sugary or high-fat samples that tend to form a skin when exposed to sudden heat. The system is rounded off by step drying, which allows you to programme different temperature plateaus; for example, to first drive off free surface water and then chemically bound crystal water separately. Automation through smart shutdown criteria Another huge advantage in day-to-day laboratory work is the intelligent automation of the drying termination process. You no longer need to stand next to the instrument and monitor the weight loss manually. The DBS 60-3 features an automatic shut-off (weight stop): The instrument terminates the measurement entirely autonomously as soon as the weight loss per unit of time falls below a minimum threshold defined by you (e.g. less than 1 mg in 60 seconds). Alternatively, you can also end the drying process purely on a time-controlled basis (e.g. exactly 15 minutes) or completely manually at the touch of a button. To save you time with recurring routine analyses, the internal programme memory can store up to 10 fully predefined drying processes. A single press of a button is all it takes for the instrument to retrieve the exact temperature, heating profile and shutdown criterion for your specific sample. Ergonomics, readability and GLP-compliant documentation The large, backlit graphic LCD display guides you intuitively through the entire measurement process in multiple languages. You can view all critical parameters in real time at any moment: the current moisture content as a percentage, the remaining weight in grams, the current actual temperature in the heating chamber, and the active drying time elapsed so far. An integrated progress indicator also visualises the status of the measurement. In professionally managed quality management systems (in accordance with GLP/ISO standards), complete traceability is essential. Via the integrated RS-232 data interface, you can easily connect the KERN DBS 60-3 to an optional dot matrix or thermal printer, as well as to a laboratory PC. At the end of each measurement, the system generates a measurement report that complies with standards, containing not only the exact results but also the date, the exact time and the balance’s individual identification number. A temperature calibration kit, available to order separately, can also be used to check the heating chamber regularly, thereby demonstrating consistent conditions for audits. Technical data Weighing range (max): 60 g Weight readability (d): 0.001 g Moisture readability: 0.01 % Reproducibility (2 g sample): 0.15 % Reproducibility (10 g sample): 0.02 % Heating technology: Halogen quartz glass heater (400 watts) Temperature range: 50 °C to 200 °C (selectable in 1 °C increments) Drying modes: Standard, Fast, Gentle, Stages Shut-off criteria: Automatic, Timed, Manual Programme memory: 10 memory slots for complete drying cycles Display: Large graphic LCD, backlit (digit height 15 mm) Sample dishes: Ø 90 mm Interface: RS-232 for PC or printer Dimensions (W×D×H): 204 × 336 × 167 mm Net weight: approx. 4.6 kg Contents 1 x KERN DBS 60-3 halogen moisture analyser 10 x aluminium sample dishes (Ø 90 mm) 1 x protective cover for the keypad 1 x mains lead 1 x Detailed operating instructions / application manual Individual requirements & accessories Please note that the 10 aluminium dishes supplied will be used up quickly. We strongly recommend ordering a bulk pack (e.g. 80 pieces) of the original KERN aluminium sample dishes (Ø 90 mm) at the same time. Do you work with samples that splash heavily, contain grease or are very liquid? If so, optimise your results by using KERN glass fibre round filters. These distribute the liquid evenly and significantly speed up the drying process. Please feel free to contact our procurement service for accessories or a DAkkS calibration certificate.

KERN OKM 173 Metallurgical Microscope, reflected light, trinocular, infinite-corrected optics
Geometric Optics of Metallurgical Reflected-Light Microscopy In materials science fractography, metallurgical quality control and the examination of opaque (light-impermeable) semiconductor structures, conventional transmitted-light microscopes fail due to the total physical absorption of photons within the solid. The KERN OKM 173 is designed as a high-precision metallurgical epi-illumination microscope. In this complex optical setup, the objective lens also functions as a condenser. The integrated 30-watt halogen light source emits a continuous, broadband spectrum of photons. This light is precisely directed into the optical axis via a partially transparent beam splitter in the microscope stand, focused onto the sample through the objective lens and reflected by the metallic solid-state surface. The reflected light passes through the objective lens once more and produces, in the trinocular tube, an image of the microscopic grain structures, voids or microcracks that is exceptionally high-contrast and free of artefacts. Physical superiority of the infinity-corrected optical path The metrological heart of the OKM 173 is its infinity-corrected optical system (Infinity Optics). In contrast to finite optical systems with a fixed tube length (e.g. 160 mm), with infinity optics the light rays emerge from the objective as parallel beams. Only a specially calculated tube lens in the microscope head focuses these parallel photons into a real intermediate image. This physical space occupied by the parallel rays between the objective and the tube lens is of essential importance: it allows additional optical components – such as polarising filters, analysers or DIC prisms – to be introduced without causing a shift in the optical focal length, spherical aberrations (aberrations) or microscopic ghost images. Polarisation optics and anisotropy analysis Particularly with reflective metallic surfaces or polished micrographs, unpolarised halogen light often leads to severe flare, which masks the finest phase boundaries in the metal lattice. The OKM 173 is therefore equipped as standard with a high-performance polarisation and analyser unit. The polariser forces the transverse electromagnetic light waves into a defined plane of oscillation. Reflection off the anisotropic crystal structure of the metal sample specifically alters the polarisation state of the light. The downstream analyser physically blocks out interfering specular reflections and makes optical stress-induced birefringence, grain boundaries and heterogeneous alloy phases visible with maximum microscopic contrast. Planachromatic optics and digital image conversion To reproduce the absolutely flat polished surfaces typical of metallurgy without geometric errors, the system is equipped with planachromatic objectives. These highly complex lens systems correct chromatic aberration for two spectral colours and physically flatten the image field so that both the centre and the extreme peripheral areas of the solid-state sample are simultaneously in absolutely sharp focus. The trinocular Siedentopf tube also enables simultaneous binocular visual inspection by the user and the loss-free coupling of the photon flux to a digital microscope camera (C-mount). This is essential for comprehensive digital documentation and software-based metrology in certified laboratories.

SAUTER JCT 100 coating thickness gauge, Fe/NFe combination sensor, internal measuring cell
Uncompromising precision in surface technology: the SAUTER JCT 100 coating thickness gauge In modern industrial manufacturing, rigorous quality assurance, professional vehicle assessment and heavy-duty corrosion protection, the accurate and non-destructive measurement of coating thicknesses is an absolutely business-critical factor. Whether it is the thickness of a protective zinc coating on a steel girder, the uniform paint finish on a car body, or the anodised layer on an aluminium profile – even minute deviations from the specified tolerance values can have dramatic consequences. A coating that is too thin will inevitably lead to premature corrosion, material fatigue and costly warranty claims. A coating that is too thick, on the other hand, is prone to flaking, compromises the mechanical fit of components and, in mass production, wastes immense quantities of expensive raw materials (such as powder coating or zinc). To completely eliminate these massive quality and financial risks, KERN & SOHN has developed the JCT 100 digital coating thickness gauge (MPN JCT 100) under its specialist brand SAUTER. This compact, ergonomic and technologically advanced handheld measuring device provides you with absolutely reliable, digital readings within milliseconds and is the perfect solution for any professional user who needs to record high-precision, standards-compliant coating data on a daily basis. Intelligent dual technology: automatic Fe and NFe detection The greatest technological advantage of the SAUTER JCT 100 is its highly advanced, universal combination measuring cell. In industrial practice, one is constantly dealing with completely different base materials. The device therefore masters both relevant physical measurement principles to perfection. On the one hand, it uses the magnetic-inductive method (Fe mode) to measure non-magnetic coatings (such as varnish, paint, plastic, enamel, chrome, copper or zinc) on magnetic base materials such as steel and iron. On the other hand, the electronics switch instantly to the eddy current method (NFe mode) when you need to measure insulating layers (such as paint, anodised aluminium, plastic or ceramics) on non-magnetic metals such as aluminium, brass, copper or non-magnetic stainless steel. The real highlight for the user: the SAUTER JCT 100 detects the respective metallic base material (substrate) completely automatically! You do not need to manually reprogram the device when switching from a steel sheet to an aluminium component. Simply place the device on the component, and the internal microprocessor automatically selects the correct physical measurement mode. This massively speeds up the testing process on mixed assemblies (for example, on modern car bodies made from a combination of steel and aluminium) and categorically rules out critical measurement errors caused by the operator selecting the wrong mode manually. Ergonomics and precision thanks to an internal measuring cell The SAUTER JCT 100 has been deliberately designed as a compact, one-handed measuring device with an internally mounted measuring cell (probe). In the harsh realities of everyday industrial use, this design offers decisive advantages over devices with external cable probes. Firstly, it eliminates the hassle of handling delicate cables that could get caught on sharp edges or break. Secondly, the internal probe enables extremely stable and wobble-free one-handed operation. You can hold on with your free hand whilst, for example, carrying out measurements on a large silo or a bridge pier whilst standing on a ladder. The tip of the probe is also fitted with a special, wear-resistant V-groove. This sophisticated design ensures that you can always position the device perfectly centred and at an exact 90-degree angle, not only on perfectly flat metal sheets but also on heavily curved surfaces, round pipes, shafts or convex body panels. Only a perfectly vertical positioning guarantees physically correct and reproducible coating thickness readings. Comprehensive statistical analyses and alarm functions In professional quality control, a single measurement is often insufficient to assess the uniformity of a coating across a large area. The SAUTER JCT 100 is therefore equipped with a generous internal data memory and powerful statistical functions. During a series of measurements, the device automatically calculates the mean value, the absolute highest measured value (Max), the lowest value (Min) and the standard deviation. This allows you to immediately identify whether a painting robot is operating unevenly in production or whether paint drips have formed. To further optimise the workflow in series testing, the device features a freely programmable limit value function (limit alarm). You define a minimum and maximum film thickness in advance (for example, 80 µm to 120 µm). If a measured value falls outside this strict tolerance range, the device immediately alerts you with a highly visible visual and audible signal. This enables extremely rapid ‘pass/fail’ sorting of components at goods-in, without you having to analytically evaluate every single numerical value on the display. Calibration and GLP/ISO-compliant documentation For companies certified to the strict quality standards of DIN EN ISO 9001, the verifiable accuracy of test equipment is of the utmost importance. The SAUTER JCT 100 can be calibrated quickly and easily by the user at any time. The comprehensive scope of supply includes both zeroing plates (for Fe and NFe) and a set of high-precision calibration foils in various defined thicknesses. This allows you to precisely adjust the device to the expected measurement range and the surface roughness of your specific workpiece using a one-point or two-point calibration. The high-resolution, high-contrast display ensures that you can always read the results perfectly, even in poor lighting conditions in production halls or in bright sunlight on a building site. The SAUTER JCT 100 is therefore not just a measuring device, but an indispensable, cost-effective tool for active quality assurance, for preventing rejects and for the long-term protection of your brand’s reputation. Technical specifications Measurement principles: Magnetic induction (Fe) and eddy current (NFe) Detection: Automatic detection of the base material (Fe/NFe) Measurement range: Typically 0 to 2000 µm (please refer to the data sheet for exact manufacturer’s specifications) Resolution (d): 0.1 µm (in the lower range) / 1 µm (in the upper range) Accuracy: approx. ± (1 to 3 % of the measured value + 1 µm) Measuring cell: Internally mounted (robust, one-handed operation) Contact surface: With V-groove for precise measurement on round parts (tubes, shafts) Statistical functions: Number of measurements, mean, max, min, standard deviation Limit alarm: Visual and audible signal when values exceed or fall below limits Calibration: Zero point and gauge calibration (two-point) Units: Switchable between µm (micrometres) and mil (mils) Power supply: Standard batteries (with auto-off function to conserve power) Contents 1 x SAUTER JCT 100 coating thickness gauge 1 x calibration set (reference plates for Fe and NFe) 1 x set of calibration spacer sheets (various thicknesses) 1 x set of batteries 1 x Sturdy hard-shell carrying case 1 x Detailed operating instructions in German Individual requirements & accessories If you are using this precision instrument as part of a certified ISO 9001 quality management system, we strongly recommend that you also order an official factory calibration certificate (ISO). This certifies the traceability of the measured values to national standards. Should you require a device with a flexible, external cable probe for specialised geometric components (such as deep bores or hard-to-reach interior body cavities), we would be happy to advise you on the sister models from the SAUTER range.

Sauter Leeb HK-DB hardness tester for metals, portable hardness tester
The Sauter Leeb HK-DB hardness tester (MPN HK-DB) is a highly sophisticated mechatronic, metrologically precise and fully portable system solution for the non-destructive hardness testing of metallic materials. Based on the physical principle of the dynamic rebound method (according to Dietmar Leeb), this compact instrument enables highly reproducible hardness measurements to be carried out directly on site on solid components, heavy machinery parts or during incoming goods inspection. For demanding metallurgical tests in the foundry industry, mechanical engineering, steel construction and automotive quality control, this digital hardness testing system provides the metrological basis for monitoring material quality in a way that is gentle on the material, process-reliable and compliant with standards. The Leeb rebound principle for precise materials analysis The technical foundation of the HK-DB is based on the precise measurement of the transient velocity of a spring-driven impact body. A standardised carbide impact body is propelled by spring force against the surface of the test specimen. Upon impact, the body undergoes elastic deformation and rebounds. The flight velocities immediately before and after impact are measured inductively. The microprocessor control system generates the Leeb hardness value (HL) from the ratio of these two velocities. This dynamic measurement method is ideally suited to a wide range of metallic alloys such as steel, stainless steel, cast iron, aluminium, brass, bronze and copper. Universal scale conversion and smart data interfaces An outstanding metrological feature of the Sauter HK-DB is the automatic, error-free real-time conversion of the primary Leeb hardness value into all internationally recognised hardness scales. Users can view the measurement results directly on the high-contrast digital LCD display in Rockwell (HRC and HRB), Vickers (HV), Brinell (HB) or Shore (HS). To support seamless quality management in accordance with ISO 9001, the instrument features an integrated measurement data memory. Via the integrated USB interface, the transient test data can be reliably transferred to a higher-level B2B merchandise management system or documentation software. Robust design for harsh industrial environments The mechatronic system architecture of the HK-DB is consistently designed for maximum service life in continuous industrial use. The ergonomically shaped housing reliably protects the sensitive control electronics from mechanical vibrations, transient impacts and dusty environmental conditions in the production area. The external impact body of type D (impact device D), supplied as standard, guarantees a consistently constant impact energy thanks to its precise mechanical guidance. For laboratory managers and those responsible for audits, Sauter offers, with this system, a reliable, validatable test medium for reproducible material testing. Technical details Measurement system & sensors Test method: Leeb dynamic rebound method Impact device / sensor: Type D (standard impact device with carbide test tip) Measurement accuracy: ±1 per cent at HL=800 (high reproducibility) Displayable hardness scales: HL (Leeb), HRC (Rockwell C), HRB (Rockwell B), HV (Vickers), HB (Brinell), HS (Shore) Measuring range: Scalable across all common metal hardnesses, depending on the material Electronics, geometry & interfaces Display type: Large, backlit digital LCD display Data storage: Internal memory for transient measurement series and individual values Digital interface: USB data output for connection to a PC Dimensions (W x D x H): 150 x 80 x 30 mm Power supply: Battery-powered (for maximum portability) Net weight: approx. 0.45 kg (compact and lightweight for mobile test cycles) Material compatibility Testable materials: steel, tool steel, stainless steel, grey cast iron, ductile cast iron, cast aluminium, brass, bronze, forged copper alloys Test specimen requirements: Minimum weight of 5 kg (for solid components) or, for thinner specimens, attachment to a stable base using coupling paste Scope of supply 1 x Sauter Leeb HK-DB hardness tester (main unit, MPN: HK-DB) 1 x External impact device, Type D 1 x Hardness comparison plate (Leeb test block for internal functional testing) 1 x Robust transport and storage case 1 x USB connection cable 1 x Detailed operating instructions / calibration guide Customised requirements & accessories To ensure the Sauter HK-DB is optimally integrated into your specific testing processes, we offer a comprehensive range of compatible system peripherals: Hardness comparison blocks: DAkkS-certified calibration blocks in various hardness ranges for audit-compliant verification of your measuring equipment in accordance with quality management guidelines.

KERN PNJ 3000-2M Precision Balance, tuning fork measurement system, internal calibration, suitable for verification
The KERN PNJ 3000-2M precision balance represents a high-end metrological system solution for high-precision weighing applications in laboratories, industrial quality control and in legally regulated, calibration-required environments. Based on the innovative tuning-fork principle, this measuring instrument combines outstanding thermal stability with mechanical robustness and extremely short settling times. Wherever reliable mass measurements up to a maximum weighing range of 3,200 grams are required in a professional B2B environment, this laboratory balance guarantees gentle handling of materials, efficient operation and process reliability of the highest standard. Innovative tuning fork measuring system and thermodynamic stability The metrological foundation of the PNJ 3000-2M is its highly advanced tuning fork measurement system (Tuning Fork Technology). In direct comparison to conventional strain gauges or electromagnetic force-compensating load cells, this system operates using an oscillating quartz tuning fork. By coupling the change in mechanical frequency to the applied load, a transient, digital measurement value is generated, operating with virtually no wear. The system is characterised by excellent resistance to fluctuations in ambient temperature, achieves a remarkable settling time of just around 3 seconds, and saves valuable waiting time during sequential measurement series in the demanding day-to-day laboratory environment. Automatic internal calibration for seamless GLP compliance A key functional feature of the balance is the integrated, automatic internal adjustment (indicated by the ‘J’ in the model designation). The system continuously monitors the thermodynamic conditions and, upon detecting a temperature change or at predefined time intervals, initiates a fully automatic calibration using an internal calibration weight. Alternatively, this adjustment process can be triggered manually at any time at the touch of a button. For quality management personnel, this ensures seamless GLP/GMP compliance, as the balance independently safeguards its metrological chain and reliably eliminates measurement drifts. Verifiable system architecture and ergonomic design The PNJ 3000-2M has a type approval for verification in accordance with European accuracy class II. With a verification value of 0.1 gram and a readability of 0.01 gram, it meets all legal requirements for use in pharmacies (compounding balance), in the precious metals trade or for official analyses. The balance is fitted with a generous, square weighing pan made of stainless steel (190 x 190 mm), which allows for easy and residue-free cleaning.

KERN CPE 15K-3 Compact Counting Scale, 15 kg / 0.5 g, 3 displays
Counting instead of weighing: the KERN CPE 15K-3 for stock-taking and warehousing The KERN CPE 15K-3 is a professional compact counting balance, specially developed for fast and error-free use in order picking, stocktaking or production. Where items used to be laboriously counted by hand (e.g. screws, electronic components or plastic parts), the CPE delivers the exact result in a fraction of a second. With a weighing range of 15 kg and a readability of 0.5 g, it perfectly covers the most important range of items in a small parts warehouse. The 3-display concept: everything at a glance The biggest advantage of a genuine counting balance over a standard balance with a counting function is the three separate displays. You can keep an eye on all the relevant values at all times without having to press any buttons: Total weight: How much does the entire weighing pan weigh? Reference weight: How much does a single item weigh (unit weight)? Total number of items: How many items are on the scale? The large, backlit LCD displays are easy to read even in dark warehouses. Efficiency through memory and target function PLU memory: Do you frequently count the same items? The KERN CPE has 100 item memory slots (PLU) for reference weights and tare deductions. Simply call up the item at the touch of a button – this saves a huge amount of time. Fill-to-Target (target counting function): Do you need to pack parcels containing exactly 1,000 screws? Programme in the target quantity. An audible and visual signal alerts you as soon as the target value is reached. This prevents overfilling or underfilling. High mobility: Thanks to the integrated rechargeable battery (optional/standard depending on configuration – please check) and the compact design, you can take the scale straight to the shelf location. Robust and practical The large stainless steel weighing plate (315 x 215 mm) is hard-wearing, easy to clean and offers enough space for counting trays or cardboard boxes. A dirt-repellent protective cover shields the keypad and housing from dust and scratches in harsh industrial environments. The counting resolution of 30,000 counts ensures that even very light parts weighing from 0.5 g are reliably measured. Areas of application Warehousing & Logistics: Stocktaking, incoming goods inspection, order picking. Production: Counting assembly kits or small parts. Quality assurance: Checking packaging contents for completeness (shortage checks). Technical Specifications Model: CPE 15K-3 Weighing range (max): 15 kg Readability (d): 0.5 g Minimum item weight (standard): 5 g Minimum part weight (laboratory): 0.5 g Counting resolution: 30,000 counts Displays: 3 x LCD, backlit (digit height 20 mm) Memory (PLU): 100 items (for reference weights) Weighing plate: 315 x 215 mm (stainless steel) Functions: Piece counting, fill-to-target (audible/visual), taring, totalisation Housing material: plastic Dimensions (W x D x H): 315 x 350 x 125 mm Weight: approx. 3.2 kg Contents 1 x KERN CPE 15K-3 counting balance 1 x stainless steel weighing plate 1 x mains adapter 1 x safety cover 1 x user manual Individual requirements & accessories Do you require the internal battery pack for mobile use without a mains socket (up to 50 hours’ runtime)?
