500g/750g/1000g weight Pencil Hardness Tester HT-6510P
Product details
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. Referenced standard, Coating Hardness Pencil Test Method Standard Test Method for Determination of Coating Hardness by Pencil Test Method General Method for Preparing The Film 2.

Specification and principles
Load Weight 1000g /750g /500g Measurement Angle (Between Pencil and Measured Surface), 45° Three Touch Points (Two Wheels, a Pencil Core). Scratch Speed: about 1mm/s.
Usage
The instrument 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.
