Precision Weight (Mass) Standards

The weight tolerance is equal to ANSI/ASTM E617 Class 0 and exceeds OIML R 111 Class E2. This class is used as a reference standard for calibrating other reference standards and weights and is appropriate for calibrating high-precision analytical

Perfectly Designed for any kind of Balance Testing ASTM precision weights, Best Price-Performance Ratio Low magnetic permeability and high corrosion resistance ensure reliable values. All weights are made with stainless steel, no aluminum is used
