Hardness test blocks – reference blocks for hardness testers

Hardness test blocks for calibrating hardness testers

Hardness test blocks are certified reference blocks for the calibration and monitoring of hardness testers. We offer suitable hardness test blocks for Leeb/rebound testers and Vickers hardness testers, for example HLD, HLC, HLDL and HRC. This allows you to check the accuracy of your device regularly. All hardness test blocks are designed for testing the respective hardness scale. The following tables show the available hardness test blocks with type, dimensions, weight and values. You can find matching devices under hardness testers.
