This precision weight set is engineered for metrology professionals who demand reliable calibration standards. Each weight is manufactured from high-grade stainless steel with a polished finish, ensuring superior corrosion resistance and durability for consistent performance over time. The set’s tolerances conform strictly to ASTM E617-23 standards for Class 1, making it suitable for critical calibration tasks, tolerance testing, and verification checks in regulated environments.

Primary applications include the calibration and verification of high-precision analytical and semi-analytical balances (Class I and II). The set is also an excellent reference for checking ASTM Class 4, 5, and 6 weights, serving as a higher-class standard. Its robust construction allows for use in educational settings for student laboratories, as well as for rough weighing operations where a reliable known mass is needed. Each set is serialized for traceability, with the serial number applied to the accompanying protective case.
