Pencil Hardness Tester
Size:HT****0P
Applications:
Pencil Hardness Tester HT****0P applies mechanical measurement.
Keep three point touch the coating (two wheel, pencil core), and a *5 degree angle between pencil and test surface.
Push the instrument sliding, pencil draws the correspondingtrack in the coating.
In the change of different pencil marks, the hardness value of the film can be determined.

Features:
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 ***0s.
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.
