Spectrographic supplies a industry wide range of metallography equipment for cutting, mounting, grinding and polishing. We also supply quality hardness testers and microscopes. We only work with established brands and market leaders. We trial and test all our equipment, to ensure you, the client, receives only the best.
Hardness tester reference blocks are used for indirect calibration of hardness testers used for testing of metals. Indirect verification should be carried out to ensure good operation of the hardness tester using each load variable. Daily calibration should be carried out with 5 tests on a certified test block, the hardness results should be recorded and the error calculated and be within the requirements of the standard.
Our test blocks are UKAS certified and carry full certification complying to the relevant specifications.
