    Rebound Hammer (concrete hardness tester) is designed for determining the hardness of concrete in concrete and aerated concrete structures and products by the rebound method. The operating principle of the rebound hammer is based on measuring the impact of a standardized energy on the concrete surface and the rebound height (H). The accuracy of concrete hardness is determined according to calibrated dependencies between the rebound height and the compressive strength of concrete established in advance. The Rebound Hammer (concrete hardness tester) is a versatile, simple, and reliable device. It can be operated indoors and under outdoor conditions.
