Pencil Hardness Tester

The Pencil Hardness Tester is an is a simple and effective technique to evaluate the hardness and resistance to scratching of coatings.

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.

The principle of operation uses the pressure applied to allow the pencil lead to just crush and therefore repeatable results of the hardness of the coating can be obtained.

The pressure or weight applied relates to pencil lead crushing and therefore can be used for vertical coating evaluation to achieve repeatable results.

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.

Supplied with a set of 14 pencils (6B to 6H), and Carring Case.
