leeb Hardness tester

A Leeb’s Hardness Tester measures the hardness of sample material in terms of Hardness Leeb (HL), which can be converted into other Hardness units.

Testing Principle: An impact body with a spherical test tip made of tungsten carbide is propelled against the sample surface by a spring force and then rebounds back.
