Product information "Kern PNS 600-3 precision balance 620 g / 0.001 g"
The Kern PNS is a precision balance with a tuning fork weighing system, adjusted with an external weight. Three models are available: the PNS 600-3 weighs up to 620 g at 0.001 g (1 mg), the PNS 3000-2 up to 3,200 g at 0.01 g and the PNS 12000-1 up to 12,000 g at 0.1 g. All have a stabilisation time of 3 s, an LCD with 16.5 mm high digits, a stainless steel weighing plate and an RS-232 interface. The PNS 600-3 also features a large glass draught shield.
External adjustment
The CAL adjustment programme adjusts the accuracy of the balance with an external test weight; suitable test weights are available at extra cost. The PNJ series, on the other hand, features internal adjustment and an optional conformity assessment. This does not replace a calibration certificate, which is available separately (see below).
Tuning fork system, counting and capacity display
According to Kern, the tuning fork system displays the weight reading quickly and is mechanically robust. A capacity display shows as a rising bar how much of the weighing range is still free. For piece counting, the reference piece counts 10, 30, 50 and 100 are available; the automatic reference optimisation gradually improves the average value of the unit weight. Depending on the model, the minimum unit weight ranges from 1 mg to 100 mg under laboratory conditions and from 10 mg to 1 g under standard conditions (model table). Additional features include percentage determination, weighing with a tolerance range (visual signal), switchable units and GLP/ISO logging with value and time. According to the data sheet, operation is via a symbol language.
Design
The PNS 3000-2 and PNS 12000-1 are flat with a housing height of 89 mm and have a weighing pan of 190 x 190 mm. They weigh approximately 2.8 kg. The PNS 600-3 has a round weighing pan with a diameter of 140 mm and a glass draught shield with three sliding doors. The weighing chamber measures 172 x 171 x 160 mm (W x D x H); the balance is 266 mm high and weighs approximately 2.2 kg. The plastic housing has a footprint of 196 x 293 mm. The plug-in mains adaptor operates at 220 V to 240 V AC at 50 Hz and comes with country adaptors for EU, AUS, UK, US and CH. The ambient temperature may be between 5 °C and 40 °C, the humidity up to 80 %.
Typical applications
- Pharmacies: weighing with percentage determination and piece counting
- Quality control: weighing with a tolerance range and counting parts
- Electronics and precision engineering industries: counting and weighing small components
- Laboratory applications: weighing of samples and chemicals
- Dental laboratories: weighing quantities of materials
The PNS 600-3 is the model for weighing in to 1 mg with a compact footprint. Anyone weighing quantities up to 3,200 g at 0.01 g takes the PNS 3000-2, for containers up to 12,000 g the PNS 12000-1.
