Elcometer 3092 Sclerometer Hardness Tester

The Elcometer 3092 Sclerometer Hardness Tester measures the hardness of a coating by moving a Tungsten Carbide Tip over the coating with predetermined force.

The body of the hardness testing instrument contains a cursor fitted with a screw lock and a round tip, compressed by one of the four springs corresponding to the four printed scales:

  • Grey spring: 0-3N (0.671lbF)
  • Red spring: 0-10N (2.248lbF)
  • Blue spring: 0-20N (4.49lbF)
  • Green spring: 0-30N (6.74lbF)

The spring force can be set by the “collar”; compressing the spring increases the force with which the tip is pushed on to the surface of the test piece.

By making short, straight movements while gradually increasing the load, the user can observe the force at which the tip leaves a mark or destroys the coating.

Each Elcometer 3092 Sclerometer Hardness Tester is supplied in a case with a 0.75mm (0.03”) diameter tungsten carbide tip and 3 springs (grey, red and blue). An optional green spring of 0 - 30N is also available.

How to test coating hardness using the Elcometer 3092 Sclerometer Hardness Tester

A quick and effective way to test coating hardness is the Scratch method, which is completed using a sclerometer, also known as a hardness pen or durotest stylus. So, how does it work?
