Testing and Calibrating Weights

Our NIST Class "F" highly polished stainless steel test weights are of the highest quality available; they are backed by a reputation known throughout the weighinh and calibrating industry. Available in a heavy duty rugged case. Light weights (100g and lighter) are in a smaller leatherette case inside the large case. Foam is inserted between weights to keep them secure.
