Concrete Test Hammer, Power Source Electric, Display Type digital

The concrete test hammer is an instrument which can be effortlessly use, For quick and approximate calculation of the resistance to pressure of manufactured concrete products. The principles on which it works are derived from the rebound impact of a hammer on a piston which rests against the top layer of the concrete products. The more substantial the capability to endure the concrete, Greater is the rebounded impact. By reading this rebound impact on a scale and relating it to curves on graphs furnished with the instrument, The tolerance against compressive forces in mpa or psi can be located, With 20% of actual. Specifications comprises a barrel in which is housed a hammer mass attached to an impact spring which slides on a guide bar. A plunger is attached to the guide bar which is pressed against the exterior for be tested. As the piston is pressed against the surface to on reaching, Be tested the compressive strength, The hammer mass is released and rebounds to a certain extent as stated by the robustness of the surface which is indicated by a rider on a calibrated scale. A lock button fixed on the structure of the hammer locks the rider in place and the rider can be recared to zero position via the application of the same button. The equivalent compressive strength can be computed from the chart supplied. Each hammer is calibrated against at standard and works, Test hammer well for for specimen of compressive strengths 100, 700 kg/cm. The instrument, Accompanied by a grinding stone for polishing the test surface, Is supplied in carrying case.
