Rebound Hammer

Concrete Test Hammer, ideally suited for on-site tests of concrete and is widely used instrument for analyzing the uniformity and compressive strength characteristics of concrete structures and Detection of weak spots in the concrete. Rebound values are read from a scale for subsequent calculation of the mean. Compressive strength values can be read from a conversion diagram Specifications: Consists of a barrel in which is housed a hammer mass attached to an impact spring which slides on a guide barA plunger is attached to the guide bar which is pressed against the surface to be tested
As the piston is pressed against the surface to be tested, on reaching the compressive strength, the hammer mass is released and rebounds to a certain extent (according to the strength of the surface) which is indicated by a rider on a calibrated scale
