Read the dial face from above—a spring-loaded plunger on the back of these indicators retracts and extends to measure objects. These indicators have a continuous dial numbered clockwise around the face, so it’s easy to see how much a dimension increases.

For comparative measurements of a part's tolerance against a reference measurement, these indicators have a balanced dial with positive values on one side and negative values on the other side.

A granite base stabilizes these indicators. The extremely tight flatness tolerances of the granite allow for nearly frictionless workpiece movement and provide an accurate reference plane for inspection work.

A contact point on the back makes it easy to read measurements on the LCD from above.
