The machine consists of a ball of known mass dropped through a plastic tube of known height and a known diameter. The ball impacts the sample placed at the base of the tube. A sensor at the base of the tube measures the time taken by the ball from the first impact to the time taken by the ball for the second impact after the rebound. Ball sizes of the indenters: 1/16``, 1/8``, 1/4``, 1/2``
