USE OF THE OC TET COM PARA TOR

L

Mott

The Octet Comparator contains eight permanent
color standards. A test sample is inserted into the
openings in the top of the comparator. The sample
can then be compared to four color standards at
once, and the value read off the comparator. For
optimum color comparison, the comparator should
be positioned between the operator and a light
source, so that the light enters through the special
light-diffusing screen in the back of the comparator.
Avoid viewing the comparator against direct
sunlight or an irregularly lighted background.
