Class F Stainless Steel Test Weight Set with NIST Calibration Certificate; 5 kg to 1 mg

Stainless Steel Test Weights are primarily used to test commercial weighing devices by state and local weights and measures officials, device installers, and service technicians.|"Small' Weight sets where the total weight is less than 15 lb are supplied in sturdy plastic cases with a carrying handle. "Large" Weight sets where the total weight is greater than 15 lb are supplied in a case with metal reinforced corners and bottoms with padded handles for easier carrying. Weights 8 oz and above each have their own compartment within the dense foam interior. Smaller weights are contained within a smaller synthetic leather case that fits into the larger master carrying case. This case-in-a-case design helps keep smaller weights from getting lost and also allows smaller weights to be taken out of the master case and used closer to the users application.
