Product Description
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.
Measurement Principle
The Pencil Hardness Tester applies mechanical measurement. Keep three point touch the
coating (two wheel, a pencil core), and a 45 degree angle between pencil and test surface. Push
the instrument sliding, pencil draws the corresponding track in the coating. In the change of
different pencil marks, the hardness value of the film can be determined.
