Sclerometer Hardness Tester

The Elcometer 3092 Sclerometer Hardness Tester is a simple but effective gauge for determining the hardness of a large variety of coatings and surfaces.

A tungsten carbide tip (diameter 0.75 or 1.00 mm) is moved across a surface with a preset force. The force is applied by means of a spring. By using different springs, the force can vary from 0 to 30 N. The sclerometer hardness is expressed in Newton (N) or as a classification based on the lowest pressure at which a scratch can be made.
