Pencil Scratch Hardness Tester with Fixed 750 g Load

Hand-held trolley that holds a pencil at 45 degrees under a standard load for determining film hardness of paints and coatings. Used by paint labs to rate hardness on a pencil scale from 6B to 9H.

Specification

Pencils of increasing hardness are pushed across the coating until one scratches or gouges the film. The hardest pencil that does not cut through is the pencil hardness. The tester gives a consistent 750 g load and a stable angle.

• Fixed 45 degree pencil holder

• Includes a set of 14 pencils 6B to 9H
• Sharpener and abrasive paper for pencil leads
