Product information "Kern PKS 1000-1 precision balance 1,200 g / 0.1 g"
The Kern PKS is a precision balance with strain gauges, a graphic LCD and a stainless steel weighing plate. Kern lists it as a versatile balance for laboratories and the pharmaceutical industry. Nine models weigh from 300 g to 10,000 g. They differ in weighing range, readability and the size of the weighing pan. The display, operation and functions are the same across all models. These include a formulation memory, user management, an alibi memory and the KERN Universal Port (KUP) for interface modules.
Nine models, four resolution levels
The PKS 300-2 (300 g) and PKS 600-2 (600 g) have a readability of 0.01 g. The PKS 1000-1 (1,200 g), PKS 2000-1 (2,500 g), PKS 4000-1 (4,200 g), PKS 6000-1 (6,200 g) and PKS 10K-4 (10,000 g) read to 0.1 g. Two models fall outside the pattern: the PKS 6000-0 weighs up to 6,200 g at 1 g, the PKS 10K-5 up to 10,000 g at 0.05 g. The weighing pan measures 131 x 131 mm for the PKS 300-2, 600-2, 1000-1 and 2000-1 models, and 180 x 170 mm for all others. The stabilisation time is 2 s for the PKS 1000-1, 2000-1, 6000-0, 10K-4 and 10K-5, and 3 s for the remaining four.
Display, user guidance and user management
The backlit graphic LCD has 21 mm high digits and guides the user through the menu with help texts. According to the data sheet, the language is English, plus a symbol language. Settings for up to 10 users can be stored in the balance; users who are not logged in have restricted access. A time display, a capacity display and a standby function are provided.
Formulations, counting and checking
According to the data sheet, the internal memory holds 20 formulations with up to 20 ingredients each, each with name and target value. When weighing in the components of a mixture, a recalculation is possible in case of overdosing. The balance counts pieces with the reference piece counts 5, 10, 20 and 50 or with a freely entered piece count; a reference weight can be entered directly. In addition, there are percentage determination, density determination, totalising memory, statistics function and a function for averaging under unstable weighing conditions. When weighing within a tolerance range, the balance emits an audible and a visual signal. According to the data sheet, the hook for below-balance weighing is included in the scope of delivery.
Data acquisition and interfaces
The KERN Universal Port (KUP) exchanges data and control commands via multiple interfaces. According to the data sheet, the RS-232, USB device, Ethernet, WLAN and Bluetooth BLE interfaces are optional. Via the KERN Communication Protocol (KCP), controllers or computers can query and remotely control the balance, and the GLP/ISO logging records date, time and ID no. during adjustment and weighing. The alibi memory has a capacity of 250,000 memory locations. A USB keyboard or barcode scanner can be connected via the USB host port, for example for batch IDs, so that weighing values can be assigned to a batch and traced. The balance is also compatible with the Kern software EasyTouch.
Power supply and design
The balance operates via the plug-in mains adaptor (100 V to 240 V AC, 50 / 60 Hz) or on battery power using 4 AA batteries (1.5 V), which are not included in the scope of delivery. According to the data sheet, the batteries last for about 20 h. An internal Li-ion rechargeable battery (YKR-01) is optionally available, with 8 h charging time and 24 h operating time with backlight (48 h without). The automatic switch-off in battery and rechargeable battery operation can be set to 30 s, 1, 2, 5, 30 or 60 min. The housing is made of plastic and measures 205 x 315 x 95 mm (W x D x H). For the PKS 1000-1, Kern also provides dimensions including the draught shield: height 180 mm, internal dimensions of the draught shield 145 x 145 x 80 mm.
Typical applications
- Laboratories: weighing, piece counting and density determination at the workstation
- Pharmaceutical industry: formulations with stored target values, logging according to GLP/ISO
- Quality control laboratories: weighing with tolerance range, statistics and alibi memory
- Batch allocation: assign weighing values to a batch via barcode scanner or keyboard
For fine weighing in, the PKS 300-2 and PKS 600-2 are intended. Anyone weighing larger quantities up to 10,000 g takes the PKS 10K-4 or, for 0.05 g, the PKS 10K-5. The PKS 10K-5 has the smallest USP minimum sample weight among the 10,000 g models (100 g compared with 200 g). The PKS 6000-0 with 1 g readability suits coarse weighings up to 6,200 g.
