Hardness Tester

This Hardness Tester is particularly useful for large, coarse grained materials, forged parts and all types of cast materials because the spherical tip of the impact device processes the characteristics of the casting structure better. It measures the velocity of a propelled impact body directly before and after the impact onto the test material’s surface; the impact creates a plastic deformation of the surface, i.e. an indentation, due to which the impact body loses part of its original speed – or energy. The ratio between both velocities indicates the hardness of the material (it will lose more velocity when creating a bigger indentation on softer material).
