WEIGHT SETS CLASS E 1 Ohaus (30390908)

WEIGHT SETS CLASS E 1 Ohaus (30390908)

The WEIGHT SETS CLASS E 1 Ohaus (30390908) is a high-capacity, ultra-precision calibration weight set engineered for accurate mass calibration and verification of analytical balances, precision balances, and mass comparators. Fully compliant with OIML Class E1 requirements and supplied with an ISO/IEC 17025 accredited calibration certificate, this set delivers excellent traceability, stability, and confidence for regulated laboratory and metrology applications.

This E1 weight set covers a focused mass range from 1 g up to 10 kg, with a total set capacity of 21.11 kg, making it ideal for higher-capacity balance calibration while maintaining strict accuracy standards. Each weight is manufactured using one-piece construction to minimize uncertainty and ensure long-term dimensional stability. Produced from Troemner Alloy 8, the weights offer uniform density, corrosion resistance, and consistent performance over extended service life. All components are securely housed in a robust protective case for safe handling, storage, and transport.
