The concrete test hammer provides a quick, simple and inexpensive method for non-destructive evaluation of concrete compression strength and other masonry materials.
Concrete test hammers are one of the most widely used instruments in the field of non-destructive testing and Elcometer offer both mechanical and digital models.
This gauge consists of a spring loaded plunger which, when released, strikes the surface with fixed and constant impact energy. During the rebound stroke, the mass moves a pointer that indicates the maximum point of return and at the same time indicates a reference value called Rebound Number.
This number, converted by the correlations available on the hammer, gives the compression resistance value in respect of the impact angle.
Key Features:
Impact Energy 2.207 Nm
Supplied with grinding stone to prepare test surface
Aluminium body
Rebound value indicated on test hammer
Rebound value chart on body, for quick calculation of compressive strength
Curve selection on chart dependant on testing angle
