This precision calibration weight is manufactured to serve as a primary standard in demanding laboratory and metrology environments. Its strict adherence to ASTM Class 1 tolerances ensures it provides a known, reliable mass value, making it indispensable for the critical tasks of calibrating high-precision balances, performing routine tolerance checks, and verifying the accuracy of other working standard weights.

The weight’s construction includes a sealed adjustment cavity, which allows for fine-tuning at the factory to achieve its exact nominal value. This value is permanently marked on the weight for clear identification. Packaged as a complete kit with a durable storage case and a handling glove, the weight is protected from environmental contaminants and accidental damage, preserving its accuracy and surface integrity over its long service life. This careful packaging supports proper mass stewardship practices.
