Coating hardness is the necessary measurement for the performance of coatings. This instrument applied the pencil scratch method.

It is a fast and economical way to determine the film hardness using the drawing lead core or the pencil core. The pencil scratch

method for coating hardness testing is a common method in the world since the 1980s. In China, this test method has also been

promoted to the coating research and industrial production. The instrument can be used both in laboratory, and on site.
