ABSTRACT:
Apparatus for measuring the hardness of capsule plugs, granules and pellets, in which a power stand (11) has a base (12) and gear motor (15) for driving a replaceable probe (25) toward a test subject supported on the base. A test subject holder (27) is placed on the base for holding the test subject, and comprises spaced apart first and second support plates (28, 30) fixed relative to one another with a third support plate (29) movable therebetween to define a space variable between zero and a predetermined maximum. Accordingly, a test subject may be held on the support for testing in a selected one of a variety of modes, including crushing, bending and cutting, depending on the spacing of the plates and the probe selected.
