Gloss Measuring

In accordance with DIN 67 530 the
reflectometer value is related to a black
glass standard with a refraction index
of 1.567 (reflectometer value 100).
Reflectometers are differentiated by the
angle of illumination of the light source.
In accordance with DIN 67 530 and
ASTM D 523 the angles are set at 20

°,

60

° and 85°; each setting corresponds

to a particular application:

• Semi-gloss surfaces are measured at
an angle of 60

°. Measurements

should range between 10 and 70
gloss units.

Language US, D, F, I, E
Display can be selected to be English,
German, French, Italian or Spanish.

Mirror Mode
off:

If a gloss value exceeds
approx.190 the

haze-gloss

automatically goes to a lower
channel and takes a new mea-
surement.

on:

If only high-gloss samples
(e.g. metals) have to be mea-
sured, you will save time with the
mirror mode.

Change Calibration Value
In this mode you can calibrate against
your own mirror gloss standard with a
defined reflectometer value. (See
Chapter 5, Calibration)
