Elcometer 181 Mechanical Concrete Test Hammer
This simple to use 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.
- Impact Energy 2.207 Nm;
- Supplied with abrasive 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.
