Scleroscope
scleroscope[′skler·ə‚skōp] (engineering) An instrument used to determine the hardness of a material by measuring the height to which a standard ball rebounds from its surface when dropped from a standard height. Scleroscope an instrument for measuring the hardness of metals and other materials according to the height of the rebound of a hammer with a hard (diamond) tip falling from a specified height onto the surface of the body being tested. Hardness is measured on a scleroscope in arbitrary units proportional to the height of the hammer’s rebound. The Shore scleroscope is a well-known type used in many cases for testing large, solid steel objects having a high surface hardness when there are no portable instruments available to determine the Rockwell hardness. |
