An instrument that measures the hardness of a sample in
arbitrary terms of elasticity. A diamond tipped hammer is
allowed to fall freely down a graduated glass tube on to
the sample under test. The hardness is measured by the
height of the rebound. In another form the rebounding
hammer actuates the pointer of a scale so that the height
of the rebound is recorded.
