This 5 kg calibration weight serves as a fundamental reference standard for verifying the accuracy of high-capacity precision balances and scales. Its construction and certification to ASTM Class 1 specifications ensure it provides the minimal permissible uncertainty, making it indispensable for quality control, laboratory research, and compliance applications where measurement integrity is non-negotiable. The inclusion of a dedicated storage case and handling glove is a critical part of the kit, protecting the weight's surface from contamination and damage that could affect its mass value and traceability.
The weight incorporates a sealed adjustment cavity, a standard feature on 100 g and larger masses, which allows for precise factory setting to its exact nominal value. With a standardized density of 7.84 g/cm³, it minimizes the potential for air buoyancy errors during high-accuracy calibrations. For operations requiring individual weight tracking within a calibrated set, serial number marking is available as an optional feature to enhance asset management and documentation practices.
