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.

The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.
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.

Researchers have been interested in the relative hardness of materials for centuries, but the first formal test for mechanical hardness didn't appear until 1896, when a professor in England, Thomas Turner, invented a device called a scleroscope
, which dropped a diamond-tipped weight against a material.
