UST®
Universal Surface Tester
Basic Functions
|
Universal test instrument for determination of
micro-mechanical properties of materials and
surfaces with high local resolution.
Allows
analysis of micro-mechanical, micro-tribological and
functional properties of materials in the
submicrometer range. Abrasion, wear, scratch
resistance, micro friction, structure and haptic
parameters can be measured. The UST® is not only
used to evaluate plastics, lacquers, coatings and
fabrics, but also enables the user to measure,
evaluate and classify polymers, metals, ceramics,
textiles, rubber and biological materials.
The
Universal Surface Tester (UST®) offers
determination of different materials, functional and
surface parameters and values in one unit. Modular
expansion is readily available. |
 |
Testing method
With the
patented MISTAN®-process a material surface is
scanned mechanically along a straight line in three steps.
This way total deformation as well as elastic and permanent
deformation are recorded and evaluated.

Hardware Options
UST® 100
with load range 1 – 100 mN.
UST® 1000
with load range 10 – 1000 mN for characterisation of harder
surfaces and coatings.
