The Hoffman Scratch Hardess Tester was developed for the comparative evaluation of scratch resistance and adhesion of many types of coatings. This instrument consists of a four-wheeled carriage, a scale arm graduated from 0-20 that is attached permanently to the carriage in a counterpoised condition about the pivot axis, and a scratch tool with a sharp circular rim mounted at 45° to the flat test surface.
