This 500 mg calibration weight set serves as a fundamental tool for maintaining weighing accuracy in a variety of settings. Manufactured from stainless steel with a polished finish, the weights offer excellent durability and corrosion resistance for long-term reliability. The set conforms to the tolerances and material requirements of ASTM E617-23 for Class 4, making it suitable for a wide range of routine metrology tasks.

Primary applications include the calibration and routine verification of Class I and II laboratory balances, tolerance testing, and rough weighing operations. It is also perfectly suited for student laboratories and general verification checks where the highest class of weight is not required. The weights are marked with their nominal value, and the set is serialized at the case level for identification.
