Product information "Kern ADJ 600-C3 carat balance 600 ct / 0.001 ct"
The Kern ADJ is an analytical balance with a plastic housing, electromagnetic force compensation and internal automatic adjustment. There are two models to choose from. The ADJ 100-4 weighs up to 120 g and reads to 0.0001 g (0.1 mg). The ADJ 600-C3 is a carat balance with a weighing range of 600 ct and a readability of 0.001 ct. Both feature a backlit LCD display with 16 mm high digits and a glass draught shield with three sliding doors.
Two models for two tasks
The ADJ 100-4 has a reproducibility of 0.0002 g and a linearity of ± 0.0004 g. The weighing chamber measures 170 x 160 x 205 mm; the balance weighs approx. 5.0 kg. The ADJ 600-C3 achieves a reproducibility of 0.002 ct with a linearity of ± 0.004 ct. Its weighing chamber is shallower at 170 x 160 x 110 mm; the housing is correspondingly lower, at 210 mm instead of 330 mm in height, and the weight is approximately 4.6 kg. According to Kern, it is intended for weighing gemstones. The stabilisation time is 4 s for both.
Internal automatic adjustment
The automatic adjustment system operates using an internal weight. It adjusts when the temperature changes by 2 °C or more and additionally every 3 h. This is not a calibration certificate, which is available separately (see below). A spirit level and adjustable feet are part of the standard equipment so that the balance can be levelled precisely. It is operated via 6 keys.
Functions and connections
Besides weighing, both models offer piece counting (minimum unit weight 1 mg under laboratory conditions, 10 mg under standard conditions) and percentage determination. The units are g, ct, lb, oz, PCS and %. Data go to a printer or PC via the standard RS-232 interface. Kern does not list a USB port for the ADJ. The stainless steel weighing pan has a diameter of 90 mm.
Typical applications
- Educational institutions: simple operation via 6 keys
- Laboratory applications: weighing in portions up to 120 g at 0.1 mg (ADJ 100-4)
- Quality control: piece counting and percentage determination
- Gemstones: weighing in carats at 0.001 ct (ADJ 600-C3)
The ADJ 100-4 is suitable when portions in grams up to 120 g are needed. The ADJ 600-C3 is intended for weighing in carats.

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 ADJ, 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.
