USE OF THE OCTET COMPARATOR

The Octet Comparator contains eight permanent color standards. A testsample is inserted into the openings in the top ofthe comparator. The sample can then be

compared to four color standards at once, and thevalue read off the comparator. For optimum colorcomparison, the comparator should be positionedbetween the operator and a light source, so thatthe light enters through the special light-diffusingscreen in the back of the comparator. Avoidviewing the comparator against direct sunlight oran irregularly lighted background.
