Good Words From Good People

The most durable hardness tester

Diamond Hardness testers are the steadiest hardness testers we’ve ever used. Our laboratory purchased two diamond Rockwell hardness testers as well as three Vickers hardness testers. We bought the first Rockwell hardness tester three years back and it still works effectivelt with high repeatability.
