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 thickness.
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.
