This comprehensive 500 mg calibration weight set is manufactured to ASTM E617-23 specifications for ASTM Class 2 tolerances, providing a trusted reference standard for a variety of weighing applications. The set is constructed from high-quality stainless steel with a polished finish, ensuring long-term stability and resistance to environmental factors that could compromise mass integrity. Its primary function is to deliver reliable performance for routine calibration, tolerance testing, and verification checks of Class I and II balances, as well as ASTM Class 4, 5, and 6 weights.
Ideal for both student laboratory use and professional rough weighing operations, this set serves as a fundamental tool for maintaining measurement confidence. The weights are clearly marked with their nominal value for straightforward use. In accordance with ASTM E617-23 for this class, the individual weights are not serialized; traceability is provided via a serial number applied to the included protective case. For specialized requirements, custom-configured sets are available as build-to-order items.
