Radius and Protractor Charts

360° Radius and Angle Charts

These charts are designed to inspect radii with arcs to 180°. They are especially well suited for small radius form tools, gages and templates.

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.
