Capacity and Readability: Analytical balances from 100 g to 5000 g with readability 0.001 g to 5 g; platform balances from 3 kg to 300 kg with readability 0.1 g to 10 g.
Included Weights: Calibration weights vary by model, from milligrams to kilograms.

Calibration Weights

Weights comply with OIML R111 standard ensuring metrological accuracy, material quality, shape, identification, and maintenance.

Weight Classes and Applications

Class E2: Reference weights for high-precision analytical balances (Class I), non-magnetic stainless steel, max resolution >100,000 divisions.
Classes F1 and F2: High precision weights for analytical balances with slightly relaxed tolerances.
Class M1: Precision weights for commercial/industrial balances (Class III), made of A3 steel or brass.

Tolerances and Ranges

Tolerances range from ±0.03 mg (1 g E2) to ±1000 mg (20 kg M1). Weight sets include fractions from 1 mg to several kilograms, supplied in wooden or plastic cases.

Packaging

5 kg to 20 kg weights in padded wooden boxes.
50 g to 2 kg weights in plastic boxes.
1 g to 20 g weights individually bagged.

Mechanical Force Measuring Instruments

Designed for tension and compression force measurement.
Dual scales in grams and newtons.
Ranges: 250 g (2.5 N) to 5000 g (50 N); readability 5 g (0.05 N) to 100 g (1 N).

Critical Recommendations

Use weights compliant with OIML R111 for calibration to ensure accuracy and standardization.
Match weight class to balance class and resolution for measurement integrity.
Store weights properly in designated cases to prevent damage and contamination.
Balances with magnetic cushioning and hydrostatic weighing improve precision and usability.
Regular calibration with certified weights is essential for maintaining accuracy.
