WEIGHT SETS CLASS E 1 Ohaus (30390910)

WEIGHT SETS CLASS E 1 Ohaus (30390910)

The WEIGHT SETS CLASS E 1 Ohaus (30390910) is a high-capacity precision calibration weight set designed for accurate mass calibration of analytical balances, precision balances, and mass comparators operating at higher load ranges. Manufactured in accordance with OIML Class E1 standards and supplied with an ISO/IEC 17025 accredited calibration certificate, this set provides excellent traceability, stability, and confidence for critical laboratory and metrology applications.

This E1 weight set covers a focused mass range from 1 kg to 5 kg, with a total capacity of 10 kg, making it ideal for high-capacity balance calibration and reference verification. 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 to ensure safe handling, storage, and transport.
