Product information "Kern PDT 1000-3 precision balance 1,020 g / 0.001 g"
The Kern PDT is a precision balance with touch display, force compensation and a stainless steel weighing plate. Six models weigh from 320 g to 6,200 g. Three models have a readability of 0.001 g (1 mg): the PDT 300-3, PDT 600-3 and PDT 1000-3. Three models have a readability of 0.01 g: the PDT 2000-2, PDT 4000-2 and PDT 6000-2. All have RS-232 and USB device as standard, automatic adjustment and a range of functions for documentation. According to Kern, the range of functions qualifies the series for the pharmaceutical industry, among others.
Operation via the touch display
The backlit LCD has digits 20 mm high. According to Kern, the display can be used, for example, to switch the unit or start the adjustment. According to the data sheet, the menu is in English, plus a symbol language. A spirit level and adjustable feet are used for levelling. In addition to the taring function (manual, repeatable), there is a standby function.
Functions for counting, formulating and checking
The PDT counts pieces with the reference piece counts 5, 10, 20, 50 and 100. The minimum unit weight is 10 mg under laboratory conditions and 100 mg under standard conditions for models with a readability of 0.001 g, and 100 mg and 1 g for models with a readability of 0.01 g. In addition, there are percentage determination, density determination and the totalling function Net-Total for formulations. When weighing within a tolerance range, the balance indicates visually and audibly whether a value falls within the range. A statistics function, a peak function and a function for calculating the mean value under unstable weighing conditions are also available.
Data transmission and logging
Weighing data is transmitted to a PC or printer via RS-232 or a USB device. With the Windows Direct function, weighing values are transferred directly via a USB device to a Windows application, without the need for manual data entry. Via the KERN Communication Protocol (KCP), the balance can be queried and remotely controlled from a computer or from CRM and ERP systems. GLP/ISO logging records date, time and ID no. at adjustment and at every weighing. For data integrity, Kern lists support according to U.S. FDA 21 CFR Part 11, for example for weighing result, sample ID, user name and balance ID.
Adjustment
According to the data sheet, the automatic adjustment system reacts to a temperature deviation of 2 °C and a time interval of 4 h. It does not replace a calibration certificate, which is available separately (see below).
Models with and without a draught shield
The three models with a readability of 0.001 g have a round weighing pan (Ø 115 mm) and a glass draught shield. The weighing chamber measures 174 x 162 x 228 mm (W x D x H); with the draught shield fitted, the balance is 360 mm high and weighs approximately 6 kg. The three models with a readability of 0.01 g have a square weighing pan measuring 185 x 185 mm; at around 101 mm, they are considerably flatter and weigh approximately 3.6 kg. Kern specifies a draught shield only for the 0.001 g models. On the underside there is an eyelet for below-balance weighing; according to the data sheet, the hook is included in the scope of delivery.
Typical applications
- Laboratories: weighing and piece counting with documented adjustment
- Pharmaceutical applications: weighing with GLP/ISO protocol and data output with date, time and ID no.
- Quality control: weighing with a tolerance range and display via signal
- Chemical industry: formulations with Net-Total and density determination
- Food industry: percentage determination and piece counting
- Plastics technology: density determination and analysis with statistical function
For weighing in up to 1,020 g where milligrams count, the PDT 300-3, PDT 600-3 and PDT 1000-3 are the models. The stabilisation time is 3 s for the PDT 300-3 and PDT 600-3, and 4 s for the PDT 1000-3. Anyone weighing larger quantities up to 6,200 g at 0.01 g takes the PDT 2000-2, PDT 4000-2 or PDT 6000-2. The PDT 2000-2 has the shortest stabilisation time in the series at 2 s.
