This premium calibration weight set is engineered for metrologists and lab technicians who require the highest level of mass standards for certifying precision balances and scales. Manufactured from corrosion-resistant stainless steel and finished to a polished surface, each weight in the set conforms to the rigorous tolerances outlined in the ASTM E617-23 standard for Class 1 weights. This ensures exceptional accuracy and long-term stability, which is fundamental for maintaining ISO/GMP/GLP compliance, performing routine tolerance testing, and ensuring the integrity of your weighing processes.
Ideal applications span critical environments, including the calibration of Class I and II analytical and precision balances, the verification of ASTM Class 4, 5, and 6 working weights, and rigorous student laboratory instruction. The set's construction supports accurate air buoyancy corrections due to its documented density of 7.95 g/cm³. Whether used for initial setup, periodic verification, or investigative troubleshooting of high-capacity precision balances, this set delivers the trusted reference mass required for confident measurement outcomes. Custom set configurations are available as built-to-order solutions to meet specific capacity and increment requirements.
