Used for the non-destructive testing of hardened concrete in order to determine the strength in various parts of a structure. During operation the plunger is pressed against the surface of the concrete. This action compresses a spring which automatically releases a percussion weight striking against the plunger, and onto the surface of the concrete. This impact causes a rebound effect which is proportional to the strength of the concrete. A pointer on the scale indicates the maximum rebound point of of the percussion weight. This number is referred to the calibration curve chart on the hammer and shows the compressive strength in relation to the impact value. The test hammer is supplied complete with plastic carrying case, grinding stone and instruction manual.

Impact energy 2.207 Joule. Calibrated in MPa (N/mm2).
