1. System description and Delivery notes
Measurement units of the micro-gloss family can be
used to determine the gloss level of paint coatings,
plastics, ceramics and metal surfaces. The micro-
TRI-gloss µ additionally allows to measure the film
thickness of paint and coatings on magnetic (Fe)
and non-magnetic base metals (NFe).
Light is directed at the surface of the sample at a
defined angle and the reflected light is measured
photoelectrically (reflectometer).
Depending on the typical gloss level of the test
object, reflectometers that direct light onto the
surface at different angles (geometry) can be used.
Measurement units are equipped with standard
geometries of 20°, 60° or 85°. All three of these
geometries are integrated into the micro-TRI-gloss.
Functions described in this manual in terms of
geometry selection are only available with the three
angle device.
In addition to measuring individual gloss values, it is
also possible to record, save and statistically
evaluate series of measurements consisting of up to
999 values.
The operate button and scroll wheel are used to
control the system. System operation is supported
by display messages (autodiagnosis and error
messages).
The measurement unit conforms to the standards
DIN 67530, ISO 2813, ASTM D 523 and BS 3900
Part D 5.
