Calibration Weights

Calibration weights are designed for accurately calibrating various sized scales during and before every operation. Raptor Supplies offers these weights from brands like Rice Lake, Ohaus, Kern And Sohn, Troemner and Benchmark Scientific. They meet traceable report, ASTM, NVLAP or NIST certifications with up to Class 7 adjustment tolerances to determine the accuracy ratios and feature stainless steel, aluminium, alloy or cast iron construction for high tensile strength. These weights use metric or avoirdupois measurement types and have counterpoise, hanger, cylinder and grip handle weight styles. Choose from a wide range of these weights, available in high gloss, painted, polished and satin finishes.
