USE OF THE OCTET 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.
