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 density of 7.95 g/cm³ allows for accurate air buoyancy corrections when performing high-accuracy mass comparisons or calibrations under controlled conditions.
The included serialization on the storage case provides essential documentation for audit trails and measurement traceability to national standards. This set is a fundamental tool for quality assurance programs, enabling technicians to maintain balance performance within specified operational parameters.
