Description

Hardness Test Pencil, Model 318 C

Measure the hardness of a coating or paint with the scratch of a pencil

Due to increasing requests to a simple test with sharp tools, another version of the hardness
test pencil has been developed – Model 318 C.
By the use of sharp edged tools, the influence of their positioning angle can cause a distinctly
wide spread of results. Therefore, for enabling comparability and repeatability, only the
vertical positioning and guidance makes sense.
The hardness test rod, model 318 C can be equipped with two types of sharp-edged tool:

  • Clemen Test tip
  • Cross hatch cutting tip

The degree of hardness of paint films, plastic coatings, etc. can be accurately measured
and recorded with the Hardness Test Pencil Models; 318, 318 S and 318 C, no matter
whether on a level or curved surface, small or large. The instrument is always ready for use
and, because of it’s small size easy transportable, an asset which will be appreciated
by all concerned with hardness tests.

Uniform hardness and quality of the coating facilitate smooth-running manufacture.
Deviation from a specified hardness causes rejects, delay in production and complaints.
Developed by Robert Bosch GmbH of Stuttgart and manufactured by ERICHSEN, the
instrument permits regular quality control of protective coatings, even during processing.
