Elcometer 3025 Scratch / Shear Tester


A motorised device to test the resistance of many materials to scratching (ISO).

The tool, a conical diamond tip, is fixed beneath a beam graduated from 0 to 1000g (0 to 2.2lb) holding a sliding weight.

This tip is applied to a sample rotating at 5rpm. The tip leaves a trace and the extent of this, in relation to the load used, indicates the degree of hardness.
