Kern DAB 200-2 Halogen Moisture Analyser, 200 g / 0.01 g
The Kern DAB 200-2 moisture analyser operates using a halogen quartz glass heating element and covers a weighing range of up to 200 grams, with a readability of 0.01 grams or 0.05 per cent moisture. The measuring principle is thermogravimetric: the built-in precision balance continuously records the sample weight during drying; the instrument calculates the moisture content from the weight loss and displays the drying curve in real time on the backlit graphic display. Those who regularly test larger quantities, such as grain, animal feed or sewage sludge, will benefit from the higher capacity compared with the smaller sister model, the DAB 100-3. Halogen quartz glass heating element for short drying times A 400-watt halogen quartz glass heating element is housed in the lid. The drying temperature can be set in 1-degree increments from 40 to 199 degrees Celsius; the stabilisation time until the start of the measurement is 3 seconds. There are three drying programmes to choose from: standard drying, fast drying and gentle drying. The unit can be switched off either automatically as soon as the weight of the sample stops changing, by a timer after a set duration, or manually at the touch of a button. Halogen or infrared: choosing the right heating technology The DAB 200-2 is the halogen version of the DAB series. In addition, LT Laborhandel stocks the Kern DAB 200-2IR (item no. lt-23265), an identical model featuring infrared heating. The main difference lies in the maximum achievable drying temperature: for the infrared version, the adjustable range ends at 160 degrees Celsius, whilst for the halogen version described here, it ends at 199 degrees Celsius. For those who need samples to dry safely even at higher temperatures, such as tough or coarse-grained materials, the DAB 200-2 is the right choice. Those who work predominantly at moderate temperatures or prefer a more even, gentler application of heat will find the DAB 200-2IR to be the alternative from the same series. The weighing range, readability and operating concept are identical for both models; the only difference lies in the heating technology and the maximum possible temperature. The decision can be made regardless of capacity requirements: even those who need the smaller DAB 100-3 will find the same choice between halogen and infrared with the DAB 100-3IR (item no. lt-23263). Graphic display and memory functions The backlit graphic display, with 14-millimetre-high digits, shows the current moisture content and the drying curve whilst the measurement is in progress. Up to 15 complete drying programmes can be stored in the unit, along with memory slots for 5 measurement results and 5 sample names. The device can be connected to a printer or PC via the RS-232 serial interface to document measurement values. Weighing technology and accuracy The internal balance is designed as a single-range balance with a strain gauge system, with a resolution of 20,000 parts per full scale. Reproducibility and linearity are 0.01 grammes and ± 0.03 grammes respectively. For a measurement uncertainty of 0.1 per cent at k=2, Kern specifies a minimum sample weight of 20 grams; this is consistent with the moisture content range of 20 to 100 per cent of the sample for which this model is designed. The sample dishes have a diameter of 92 millimetres and rest on an aluminium weighing plate; the housing is made of cast aluminium and plastic. Typical applications The DAB 200-2 moisture analyser is used wherever the moisture content needs to be determined quickly and without time-consuming sample preparation, for example in the goods-in department of a grain mill or during routine checks of raw materials prior to further processing. The wide weighing range also makes the instrument suitable for bulky or irregularly shaped samples, without the need for time-consuming pre-weighing or division. Food production and the food industry Water management Energy and raw materials industry Agriculture Selection guide: DAB 100-3 or DAB 200-2 If you are undecided between the two halogen models, the main factors to consider are the weighing range and readability.

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).

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.

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 DAB 100-3 Halogen Moisture Analyser, 110 g / 0.001 g
The Kern DAB 100-3 moisture analyser is the high-resolution model in the Halogen DAB series, with a weighing range of up to 110 grams and a readability of 0.001 grams or 0.01 per cent moisture. As with the larger DAB 200-2, the instrument operates on a thermogravimetric principle: the internal balance continuously records the sample weight during drying; the instrument calculates the moisture content from the weight loss and displays the drying curve in real time on the screen. For small or high-value samples, where every tenth of a milligram counts, the finer readability is immediately noticeable compared with the larger sister model. Halogen quartz glass heating element for short drying times As with the DAB 200-2, the lid houses a 400-watt halogen quartz glass heating element. The drying temperature can be set in 1-degree increments from 40 to 199 degrees Celsius; it takes just 3 seconds for the temperature to stabilise before the actual measurement begins. You can choose between the drying programmes ‘Standard drying’, ‘Fast drying’ and ‘Gentle drying’; the unit switches off automatically when a constant weight is reached, either by a timer or manually. Halogen or infrared: choosing the right heating technology The DAB 100-3 is the halogen version of the DAB series. LT Laborhandel also stocks the Kern DAB 100-3IR (item no. lt-23263), an infrared version with the same design. The difference lies in the maximum achievable drying temperature: the infrared version reaches a maximum of 160 degrees Celsius, whilst the halogen version described here reaches 199 degrees Celsius. For samples that require higher temperatures to ensure thorough drying, the DAB 100-3 is the right choice. Those who can manage with more moderate temperatures or prefer a gentler application of heat will find the DAB 100-3IR to be the alternative from the same series, with an identical weighing range and identical readability. The same choice between halogen and infrared is also available for the larger DAB 200-2 and its counterpart, the DAB 200-2IR (item no. lt-23265), should the higher weighing range be more important than high readability. Graphical display and memory functions The backlit LCD graphic display, with 14-millimetre-high digits, shows the moisture content and drying curve whilst the measurement is in progress. The internal memory can store up to 15 drying programmes, plus 5 memory slots for measurement results and 5 for sample names. Measurement values can be transferred to a printer or PC via the RS-232 interface. Weighing technology and accuracy The balance is designed as a single-range balance with a strain gauge system, with a resolution of 110,000 parts per division, more than five times the resolution of the DAB 200-2. Reproducibility and linearity are 0.001 grammes and ± 0.003 grammes respectively. According to Kern, a minimum sample weight of 2 grams is sufficient to achieve a measurement uncertainty of 0.1 per cent at k=2, making the instrument suitable for use with small or limited sample quantities. As with the DAB 200-2, the sample dishes have a diameter of 92 millimetres; the weighing plate is made of aluminium, whilst the housing is made of cast aluminium and plastic. Typical applications The DAB 100-3 is suitable wherever small sample quantities need to be tested for moisture content quickly and with high resolution, for example during the incoming inspection of raw materials in small batches or for release testing in the laboratory. The low minimum sample weight of 2 grams ensures reliable results, even when only a small amount of sample material is available. Food production and the food industry Water management Energy and raw materials industry Agriculture Selection guide: DAB 100-3 or DAB 200-2 Within the Halogen DAB series, the DAB 100-3 and DAB 200-2 differ primarily in terms of weighing range and readout accuracy.

Those who regularly test larger or heavier samples will find the DAB 200-2 (item no. lt-23264) to be the ideal alternative with a higher capacity. Both models share the same housing, operating concept and interface, so switching between the two sizes does not alter your usual workflow. Operating conditions, storage and warranty The DAB 100-3 is designed for operation at ambient temperatures of 5 to 40 degrees Celsius and a relative humidity of 5 to 80 per cent. For storage outside of operation, for example during transport or in stock, Kern specifies a temperature range of minus 10 to 40 degrees Celsius. According to the manufacturer’s specifications, the unit contains no substances prohibited under REACH. The manufacturer’s warranty is valid for 36 months. Frequently asked questions about the DAB 100-3 What distinguishes the DAB 100-3 from the DAB 200-2?

KERN DAB 100-3IR Infrared Moisture Analyser, 110 g / 0.001 g (0.01 %)
Precision meets gentle drying: KERN DAB 100-3IR moisture analyser The KERN DAB 100-3IR (MPN DAB 100-3IR) is the specialist solution for laboratories that demand the highest standards of accuracy whilst analysing temperature-sensitive samples. With outstanding readability of 0.001 g (corresponding to 0.01% moisture) and a weighing range of up to 110 g, it meets the most demanding quality control requirements. Its key feature, however, is its heating system: a 400-watt infrared heater that dries the sample particularly gently. Why use infrared technology for high-precision measurements? With a resolution of 0.001 g, even the slightest burning of the sample dramatically distorts the measurement result. Infrared heat penetrates the sample more evenly than conventional halogen light. No burning: Dark, light-absorbing samples dry thoroughly without charring on the surface. No crust formation: With sugary or pasty substances (e.g. in food analysis), IR prevents the formation of a crust that would block the escape of residual moisture. Temperature range: The drying temperature can be precisely adjusted in 1 °C increments from 40 °C to 199 °C. Visual monitoring thanks to the graphic display Operating the DAB 100-3IR is intuitive and safe. The backlit graphic LCD guides you through the measurement process and displays all key parameters in real time: Current moisture content in % Current temperature Drying time to date Active drying programme Live display of the drying curve Efficiency through automation Save time in your day-to-day laboratory work with intelligent automation features: Shut-off criteria: The balance automatically detects when the weight remains constant and terminates the measurement. Time-controlled or manual stops can also be selected. 15 programme memories: Save complete drying profiles (temperature, stop criteria) for your 15 most common samples. A single press of a button is all it takes to start. GLP documentation: Via the RS-232 interface, reports can be sent to a printer or PC in accordance with standards (including date and time).

KERN DAB 200-2IR Infrared Moisture Analyser, 200 g / 0.01 g (0.05 %)
Gentle drying for sensitive samples: KERN DAB 200-2IR moisture analyser The KERN DAB 200-2IR (MPN DAB 200-2IR) is a specialised version of the popular KERN DAB moisture analyser. Whilst halogen lamps are designed for maximum speed, this model is fitted with a 400-watt infrared lamp. This technology offers significant advantages when analysing temperature-sensitive, strongly coloured or sugar-containing materials. Furthermore, the instrument offers an unusually large weighing range of 200 g, which significantly simplifies the analysis of bulky or heterogeneous samples. Why infrared technology? An infrared heater warms the sample more evenly and gently than an aggressive halogen heater. No burning: Dark samples (which absorb light heavily) tend to burn on the surface under halogen lighting before the moisture inside has evaporated. Infrared prevents this. No crust formation: With pasty or sugary samples, the gentle IR radiation prevents the formation of a crust that would block the escape of further moisture. Precise results: Gentle drying ensures that only the water evaporates and the sample does not undergo chemical decomposition. Readability is 0.01 g / 0.05% moisture. Full control via the graphic display The large, backlit graphic LCD guides you intuitively through the measurement process. You can see all the key values at a glance at any time: Current moisture content in % Current temperature Drying time to date Active drying programme Live display of the drying curve Routine measurements made easy The KERN DAB 200-2IR takes a lot of the work off your hands in your day-to-day laboratory routine: Shut-off criteria: The instrument automatically detects when the weight remains constant (weight stabilisation) and terminates the measurement. Alternatively, you can switch it off either by a set time (e.g. 20 minutes) or manually. Programme memory: You can store up to 15 complete drying profiles (including temperature and stop criteria). Temperature profile: Adjustable from 40 °C to 199 °C in fine 1 °C increments.
