500 mg - 1 mg Calibration Weight, ASTM Class 3

Key Highlights Designed to meet ASTM E617-13 specifications for Class 3 tolerances. Manufactured from stainless steel with a polished finish. Nominal value clearly marked on each individual weight. Density of 7.95 g/cm3 for standardized calculations. Serial numbers applied to the storage case for full traceability. Supplied as a single 500 mg weight and a single 1 mg weight. These precision calibration weights are engineered for the routine testing, calibration, and verification of high-sensitivity analytical and micro-balances. Conforming to ASTM E617-13 standards for Class 3 tolerances, they provide a certified mass standard for ensuring measurement integrity in laboratory, pharmaceutical, and research environments where minute quantities are measured. Crafted from corrosion-resistant stainless steel with a polished finish, the weights offer durability and minimal surface adsorption. The marked nominal values allow for quick identification, while the standardized densit
