|Powerful Tools for Surface Strength Evaluations on
Every Type of Material
The low test force (0.1~1960mN)
combined with a wide indentation depth range (0.001µm~10µm)
makes the DUH-201 series ultra effective for performing surface
hardness measurements on metals, plastics, rubbers, ceramics,
and many other materials.
This instrument uniquely measures dynamic indentation depth,
not the indentation after the test. This in turn permits measurement
of very thin films and surface (treatment) layers that are
impossible to measure with conventional methods. Additionally,
this same method supplies the data needed to calculate elastic
modulus on the test specimens.
Capable of measuring micro-structure constituent components
within a sample, not just overall hardness.
Measurement of materials exhibiting high light absorption,
which is difficult for conventional methods, is easily performed
on the DUH-201 series.
Rubbers and Elastomers:
Rubber hardness has traditionally been measured under a set
of fixed conditions according to JIS K6301/ISO7619 using a
rubber hardness tester. Now, the DUH-201 permits measurement
of this same amterial under various different sets of conditions.
Additionally, this instrument also permits hardness measurement
of the surface layers alone, thus providing useful information
for the study of surface deterioration.
Glasses and Ceramics:
The DUH is capable of measuring brittle samples, such as glass
and ceramics, either with or without forming cracks.
