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 a grinding stone to prepare test surface
• Aluminium body
• Rebound value indicated on test hammer
• Rebound value chart on the body, for quick calculation of compressive strength
• Curve selection on chart dependant on the testing angle
