To confirm accurate calibration of legal-for-trade scales, these test weights come with a certificate of calibration traceable to ASTM that states they’ve passed a test for accuracy. They have a handle for easy carrying and are used to calibrate legal-for-trade scales. All are marked with their weight.

Weight Bags

Filled with Sand

Filled with Stainless Steel Shot

Hold down equipment and balance loads with these bags.

Bags filled with sand are an economical choice, but their weight will change slightly over time as the sand dries out.

Bags filled with stainless steel shot have tight weight tolerances, so they can also be used as test weights.
