Features of TT-MPH Motorized Pencil Hardness Tester

Hardness of a coating film is tested by scratching its surface with graded hardness pencils.
Pencil is fixed at a 45° angle so that its lead tip contacts the surface of the coating film, with an appropriate load applied.
Sample platform moves at a constant speed (as per JIS standard, 0.5 mm/sec), allowing the coating surface to pass under the pencil tip.
Hardest pencil that does not cause damage (scratch) to the coating film is regarded as the coating film hardness.
