Kern ADS 200-4 analytical balance 220 g / 0.0001 g

The Kern ADS is an analytical balance with a touch display, glass draught shield and extensive functions. Three models weigh up to 120 g, 220 g or 320 g and read to 0.0001 g. The balance features a force compensation system, an ABS plastic housing and a backlit LCD with 20 mm high digits. According to Kern, the range of functions is suitable for the pharmaceutical industry, among others.

Touch operation and connectivity

The touch display can be used, for example, to switch the unit or start the adjustment. Via the Windows Direct function, weighing values go from the USB device port straight into a Windows application, without manual entry. An RS-232 interface is also fitted as standard. With the KERN Communication Protocol (KCP), the balance can be queried and remotely controlled by computers or CRM and ERP systems.

Functions and logging

The functions include a statistics function, weighing with tolerance range, piece counting (minimum unit weight 1 mg under laboratory conditions, 10 mg under standard conditions), percentage determination, totalising function, density determination, a hold function with averaging and below-balance weighing. The GLP/ISO report outputs date, time and ID no. during adjustment or weighing. According to Kern, the balance supports data integrity according to U.S. FDA 21 CFR Part 11, for example with weighing result, sample ID, user name and balance ID. The units include kg, g, mg, ct, lb, oz and N, 12 in total.

External adjustment and installation

The ADS is adjusted using an external weight. For the ADS 100-4, Kern lists the test weight 316-07 and the Safety Set 315-107-103. The ambient temperature is between 15 °C and 25 °C, the humidity between 15 % and 80 %. The installation site should be within this range. Assembled, the balance measures 207 x 318 x 360 mm and weighs approx. 6 kg.

Typical applications

• Pharmaceutical applications: weighing with data integrity according to FDA 21 CFR Part 11, according to Kern
• Laboratories and quality control laboratories: testing with tolerance range and GLP/ISO report
• Microanalysis and precision engineering: weighing in portions in the milligram range, counting small parts
• Material testing and the chemical, food and plastics industries: percentage and density determination
• Research and development: connection to computers via KCP and Windows Direct

Because readability and functions are the same for all three models, the weighing range decides: ADS 100-4 up to 120 g, ADS 200-4 up to 220 g, ADS 300-4 up to 320 g. Reproducibility and linearity are 0.0003 g for the first two models and 0.0004 g for the ADS 300-4. The stabilisation time rises from 3 s to 5 s.

Technical details

These values apply to all models. Deviating values are given in the model table.

Calibration and conformity assessment

A DAkkS calibration certificate (item no. 963-101) can be ordered separately. The confirmation of manufacturer specification (969-517) is only available in conjunction with the DAkkS calibration certificate. For the ADS, Kern specifies neither a verification value nor a conformity assessment under the NAWI Directive (2014/31/EU). Anyone who needs such a conformity assessment should ask for a model with this option.
