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.
Grip-Handle Test Weights

A handle makes it easy to move these test weights. They are marked with their weight.
Counterbalance Weights for Beam Scales
Add these stackable weights to the end of a beam scale to increase its total capacity. They’re also known as counterpoise weights. All are marked with their weight.
Optional hangers (sold separately) let you hang weights on beam scales.
