ABSTRACT:
The invention provides an apparatus and method for determining the hardness of a test piece supported in a predetermined position, by illuminating the test piece with an electromagnetic medium, receiving reflected medium in a television camera which provides a signal which varies in accordance with variations in intensity of the reflected medium, and electrically processing the signal to provide an output dependent upon the size of indentation which can be interpreted to determine the hardness of the test piece.
