Pencil Hardness Tester, Portable Hardness Tester, Coating
Film Hardness Meter RH-120P
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.
