The MAX hardness value of pencil leads, that leaves no any traces of destruction on the coating, is hardness value of tested coating (for example: 3H, 2H, H, HB, B, 2B, etc.).

 

Design

The instrument is made of steel, has rectangular shape. There are two castors for movement on the surface of tested object. There is a port through the instrument and thumbscrew for fixation of the pencil at an angle of 45 ° to the tested surface. The design of the device provides a constant load 7,5N (750g) of the pencil lead on the tested coating.
