Legal-for-Trade Grip-Handle Test
Weights with Calibration Certificate
To confirm accurate calibration of legal-for-trade scales, these test weights come with a certificate of calibration traceable to ASTM or NIST 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.

Grip-Handle Test Weights
A handle makes it easy to move these test weights. They are marked with their weight.
Grip-Handle Test Weights with Calibration Certificate
A certificate of calibration traceable to NIST states that these weights have passed a test for accuracy. They have a handle for easy carrying and are used to calibrate scales. All are marked with their weight.
Weight Bags
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.
