The concrete test hammer provides a quick, simple and inexpensive method for non-destructive evaluation of concrete compression strength and other masonry materials.

Concrete test hammers are one of the most widely used instruments in the field of non-destructive testing and Elcometer offer both mechanical and digital models, with Optional Calibration Certificate available. The Elcometer 181 Mechanical Concrete test hammer is comparable with the Schmidt Hammer, Type N.

This gauge consists of a spring loaded plunger which, when released, strikes the surface with fixed and constant impact energy. During the rebound stroke, the mass moves a pointer that indicates the maximum point of return and at the same time indicates a reference value called Rebound Number. This number, converted by the correlations available on the hammer, gives the compression resistance value in respect of the impact angle.
