Designed for use in the calibration of scales, Cardinal Scale’s test weights have been calibrated using reference standards tested by the State of Missouri Department of Agriculture (State Test No. 1119 & 1121) and traceable to the National Institute of Standards & Technology through NIST Test No. 259883. Use these test weights to calibrate an inaccurate scale, or just to make sure your scale is performing as accurately as it should. Calibration weights are available in 1, 5, 25, and 50 lb weights. The 25 and 50 lb test weights come with integral grip handles to ease transport. These test weights are built to Class F field standard specifications. They must be certified by a local Weights & Measures official before use on a legal-for-trade device.
