Scratch Hardness Tester TriForcePencil 293
A simple standardized method for testing surface hardness
The pencil method belongs to the group of scratch hardness testing instruments. This is a
simple and quick method for testing the surface hardness of coatings with regard to stresses
inflicted by scratching with sharp edges, or other rough surfaces.
It can also be applied during production, e. g. for coil coatings.
The equipment of the TriForcePencil 293 with three test loads ( 5 N / 7,5 N / 10 N ) instead of
usually only one ( 7,5 N ) meets the increasingly possibility of variation of the test load for this
type of testing even currently demanded in the Asian market
