Spec：	Coating hardness is the neccessary 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 th
Model：	HT-6510P

 

 Principle　

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.
