This is to determine the hardness of a metal sample by indentation method. A simple apparatus comprising an aluminium tube 750 mm long, 12.5 mm outside diameter. A standard centre punch is provided which is dropped down the tube, the lower end of which rests on a sample under test. The tube ensures that punch is dropped from a constant height and indentation to be measured with a hand microscope of approx. 30x magnification with a built in graticule.
