High Performance Hardness Tester Calibration Block / Leeb Block ISO9001
Hardness Calibration TEST BLOCK Block
Standard hardness blocks are used for calibrating hardness tester, it can check whether the readings of the hardness tester are within the scope of the international standards. Each hardness block is engraved with serial numbers, which can ensure the traceability. The hardness standard
blocks are made of high quality materials, which can ensure the reliability and stability of hardness value. We provoide various types of hardness blocks that can satisfied most requirements of hardness testing.
