Elcometer 181 Mechanical Concrete Test Hammer

Elcometer Home Page

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
