Pencil Hardness Testers

Caltech Engineering Services offers a Pencil Hardness Tester. It is an effective method to test coatings for their hardness and resistance to scratches and wear. The test method allows the use of pencils, which have a known hardness grade to be moved over the surface to be tested at a fixed angle and pressure. Traceable test method uses high quality hardness graded pencils. These pencils when passed for a specified number of times on the coating will also allow a wear factor to be determined which is related to the hardness of the pencil used. The tester is supplied in carrying case with guide bar and box of 12 quality pencils, hardness range from 6B to 6H. It is manufactured as per the international standard.
