Elcometer 501
Pencil Hardness Tester

Using the same technique of evaluation with pencils as the Elcometer 3080 , this instrument enables the pencil lead to be maintained at a constant force of 7.5N, and at the appropriate angle - which increases the reproducibility of the test.

The Elcometer 501 is supplied in a plastic carrying case and comes complete with a set of pencils in each of the 14 hardnesses from 6B to 6H, a pencil sharpener and a sandpaper block.

Can be used in accordance with:

• ASTM D 3363
