Product Description
The external diameter of a cylindrical object is measured using a ring gauge, which is a cylinder ring made of a thermally stable material, frequently steel, with an internal diameter completed to gauge tolerance. Ring gauges can be used to compare measurements as well as to inspect, calibrate, and set standards for other gauges. For master, setting, or working applications, individual ring gauges or ring gauge sets are produced in metric and English dimensions to a range of tolerance grades.
