Standard charts for the TOPIC-14, TC-10 and CLASSIC-10 are supplied with angular measuring lines. When ordering charts for the TOPIC-14, add a (-8) to the standard CX part number for 14” diameter charts.

Protractor Charts

Ideally suited for accurate angle inspecting, these 180° Protractor charts furnish a rapid and accurate inspection device which is suitable for any desired magnification setting. They can be used on comparators not equipped with angle measuring facilities. The edge type protractor chart, supplied in 14” diameter size only, has a large center area with right-angel lines so that other inspection can be combined with angle inspection using an un-graduated chart ring.
