The concrete test hammer is an instrument that is easy to use for the quick and approximate measurement of the resistance to pressure of manufactured concrete products.
The principles on which it works are based on the rebound impact of a hammer on a piston that rests against the surface of concrete products.The greater the resistance of the concrete, the greater is the rebounded impact.By reading this rebound impact on a scale and relating it to the curves or tables on the graphs supplied with the instrument, the resistance to compression in MPa or PSI can be determined.
