Analytical balances with two weighing ranges switchable on the same unit, standard RS232 and USB, and internal calibration in the N series.
- Two independent programs: 0.1 mg and 0.01 mg
- Capacity of 120 or 220 g depending on the model
- Bidirectional RS232 and USB, with export to Excel
- Internal calibration with dynamic compensation in the N series
Configurations, certifications, power supply, accessories and availability are confirmed in the quote.

Two ranges in a single body
The full range (120 or 220 g depending on the model) reads at 0.1 mg with ±0.1 mg repeatability; the fine range (up to 31 or 51 g) goes down to 0.01 mg at ±0.03 mg. That is the family's idea: the small sample is weighed ten times finer without changing instruments.
The stated linearity error is ±0.2 mg on the full range and ±0.03 mg on the fine one, with stabilization of 2 to 3 seconds depending on the range.
The N calibrates itself, and the outputs come fitted
The N versions carry internal calibration and the standard ones external; RS232 and USB are standard across the family, with a Ø90 mm pan and g, oz, ct, mg and custom units.
