WEIGHT SETS CLASS E 1 Ohaus (30390913)

WEIGHT SETS CLASS E 1 Ohaus (30390913)

The WEIGHT SETS CLASS E 1 Ohaus (30390913) is a high-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 ensures excellent traceability, stability, and long-term reliability for professional laboratory and metrology use.

This E1 weight set covers a practical mass range from 1 g up to 2 kg with a total set capacity of 4 kg. Each weight is manufactured using one-piece construction to minimize uncertainty and provide superior mechanical stability. Produced from Troemner Alloy 8, the weights offer uniform density, corrosion resistance, and consistent performance over extended periods. All components are securely arranged in a robust protective case for safe handling, storage, and transport.
