Abstract
An apparatus for testing the surface hardness of construction materials, comprising a body, an element mounted on said body and intended to be placed against the surface to be tested, a hammer movable longitudinally on said body to produce an impact against the surface to be tested, an elastic propelling element between the body and the hammer to propel it, and an indicator fixed to the body to measure the intensity of the rebound of the hammer after impact.
