Sclerometer

The sclerometer, also known as the Turner-sclerometer (from Ancient Greek: ? meaning "hard"), is an instrument used by metallurgists, material scientists and mineralogists to measure the scratch hardness of materials. It was invented in 1896 by Thomas Turner (1861-1951), the first Professor of metallurgy in Britain, at the University of Birmingham.

The Turner-Sclerometer test consists of microscopically measuring the width of a scratch made by a diamond under a fixed load, and drawn across the face of the specimen under fixed conditions.[1]
