WEIGHT SETS CLASS E 1 Ohaus (30390037)

WEIGHT SETS CLASS E 1 Ohaus (30390037)

The WEIGHT SETS CLASS E 1 Ohaus (30390037) is a high-capacity, ultra-precision calibration weight set engineered for accurate mass calibration and verification of analytical balances, precision balances, and mass comparators. Manufactured to comply with OIML Class E1 requirements and supplied with an ISO/IEC 17025 accredited calibration certificate, this set delivers excellent traceability, stability, and long-term reliability for demanding metrology applications.

This E1 weight set spans from 1 g up to 2 kg, including duplicate 2 kg weights, with a total set capacity of 6.11 kg. Each weight is produced with one-piece construction to minimize uncertainty and ensure mechanical robustness. Made from Troemner Alloy 8, the weights provide uniform density, corrosion resistance, and consistent performance over extended use. All components are neatly arranged in a durable protective case to ensure safe handling, storage, and transport.
