The 25 kg – 1 g Calibration Weight, ASTM Class 1 is engineered to serve as a dependable reference standard for routine calibration and verification procedures. Manufactured in full compliance with ASTM E617-23, this weight is suitable for a broad range of applications where consistent and traceable accuracy is required, from educational laboratories to industrial quality control.
The kit includes the single weight packaged in a protective case or vial, along with a handling glove to prevent contamination. The weights feature a polished stainless steel finish for Classes 0 through 4 and a satin finish for Classes 5 through 7, ensuring durability and stability. In accordance with ASTM standards, weights in Classes 1 through 7 are clearly marked with their nominal value for easy identification during use.
This calibration weight is commonly utilized for the calibration of Class I and II analytical and precision balances, as a higher-class reference for ASTM Class 4, 5, and 6 working weights, in student laboratories for training, for rough weighing operations in production environments, and for periodic tolerance testing and verification checks to ensure ongoing scale performance.
