Apparatus is disclosed for measuring compressive loads and more specifically for measuring the "diametral load to close", of a gapped piston ring or sealing ring. The ring is mounted in a vertical plane so that the diameter through its gap is substantially horizontal. At the opposite ends of the vertical diameter, the ring is supported by, and makes contact with, upper and lower slide members which are movable towards and away from each other in a vertical direction. The lower slide rests on a load cell. A compressive load may be applied to the piston ring through the upper slide so as to close the piston ring gap, and the compressive load is registered by the load cell.
