Designed to evaluate resistance to
scratching. A tool fitted with a
hemispherical ball of 1mm diameter
(standard) is lowered gradually onto the
surface of the sample and moved 6cm.
Depending on the purpose of the test
and the load applied, varying degrees of
penetration of the tool into the coating
are observed, from a superficial trace to
total destruction.
The Elcometer 3000 is available in two
versions; the original Manual Clemen
Unit and the Motorised Clemen Unit.
See also the Elcometer 1535
Multifunction Scratching Tool.
Elcometer 3000/1 Manual Clemen Unit;
The tool is positioned on the sample,
which is fixed on a sliding platform and
moved manually. Load variable from
0 to 2000g.
Elcometer 3000/3 Motorised Clemen
Unit: The motorised motion brings the
tool gently in contact with the sample,
whatever the load, variable from
0 to 5000g, and moves it across the
coating, with automatic start and stop.
The contact of the tool with the metallic
substrate is indicated by a lamp and
voltmeter.

• Available as either a manual or
motorised version.
• Variable load adjustment and
interchangeable scratch tool.
• Used to evaluate resistance to
scratching. |
Improved mechanical
resistance is part of many
quality requirements. One
important criteria for
assessing this feature is
hardness.
Depending on the
requirements there are
various methods for testing
hardness.
Some are
dedicated to characterise
coatings and others are more
suitable for testing bulk
materials such as metals,
plastics, rubber or elastomers.
Elcometer manufacture and
supply a wide range of
instrumentation designed for
the hardness tests most
frequently used in the industry
– these include pendulum,
scratching, indentation or
rebound measuring methods. |
