Abstract
A non-contact sensor is attached to the indenting module with its working range encompassing the tip of the indenter. The sensor directly measures penetration depth of the indenter during scratch, wear or instrumented hardness testing. During the test, the non-contact sensor records the height of the surface as the indenter penetrates the surface of the testing specimen.
