INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780302)

INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780302)

The INDIVIDUAL WEIGHT CLASS E 2 Ohaus (80780302) is a designed for laboratories that require excellent measurement accuracy and traceability. Manufactured in the USA, this weight meets OIML E2 standards and is suitable for calibrating analytical and high-resolution precision balances used in research, quality control, and metrology environments.

This weight features a cylindrical, one-piece construction made from Troemner Alloy 8, a premium material known for its high density, dimensional stability, and long-term resistance to wear and corrosion. The one-piece design minimizes the risk of mass variation over time and ensures consistent performance during repeated calibration procedures. With a density of 8.03 g/cm³ at 20°C, it provides stable handling characteristics and reliable mass consistency.

To maintain accuracy and protect the surface finish, the weight is supplied with a dedicated protective case. This case helps prevent contamination, scratches, and environmental effects that could influence measurement uncertainty. The compact dimensions also make it easy to store and handle during routine calibration work.
