Brinell Test Blocks and Accessories

All of our Brinell Test Blocks come certified to applicable standards. We adhere to a strict procedure for the calibration of these blocks, and the accuracy of the tester is maintained using a proving ring and load cell both traceable to N.I.S.T. The readings themselves are done using a stage micrometer also calibrated and traceable to N.I.S.T.

Master Calibration Kits

Our Master Calibration Kits are produced to provide our customers with the ultimate tool in Quality Control. Each kit contains a test block or blocks and the actual indenter unit that was used to calibrate them. By matching specific blocks to a specific indenter, a set relationship is established, and they can be eliminated as potential variables in the hardness test system. Should a problem arise, a master kit on hand allows you to quickly and accurately determine whether your hardness tester is the source.

Each block in our kits has been calibrated on a tester whose accuracy has been verified using N.I.S.T. traceable load and depth measuring devices. The individual test blocks are marked both with their own unique serial number AND the serial number of the indenter in the kit. All of our kits come with their own polished wood case, and certified to all the applicable standards.
