Hardness Testers

Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when force is applied. Obviously, some materials are harder than others, but to define levels of hardness, a hardness tester is used. A hardness tester tests scratch hardness, indentation hardness, and rebound hardness and they are each tested in different ways. In scratch hardness testing, the most common test is Mohs scale, which is used in mineralogy. In indentation testing, tests are performed on a scale known as Rockwell, Vickers, Shore, and Brinell. While in rebound hardness testing, the device used to take this measurement is known as a scleroscope. Hardness testers are utilised in the fields of engineering and metallurgy.
