Overview - Elcometer 3000 User Manual

1 OVERVIEW

Available in two versions; Manual and Motorised, the Elcometer 3000
Clemen Unit is a robust and simple-to-use instrument for evaluation of
the resistance to scratching of a coated surface. The sample can be
metal, wood, glass, plastic or other hard materials.
A tool fitted with a hemispherical ball is lowered gradually onto the
surface of the sample and moved in a straight line a distance of 60mm
(2.4"). The downward force exerted by the tool onto the surface is
adjustable by means of a sliding weight.
Depending on the purpose of the test and the force applied, varying
degrees of penetration of the tool into the coating are observed, from a
superficial trace to total destruction.
Elcometer 3000 Manual Clemen Unit: The sample is clamped
to a sliding platform which is moved manually.
Elcometer 3000 Motorised Clemen Unit: The sample is
clamped to a fixed platform. At the press of a button, the tool is
moved across the sample and stops automatically at the end of
its travel. Contact between the tool and a metallic sample is
indicated by a lamp and voltmeter.
