Starrett Plus/Minus Dial Plunger-Style Variance Indicators


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 spring-loaded plunger retracts and extends to measure objects. All have highly sensitive, wear-resistant jeweled bearings for a long service life. Rotate the dial face for viewing at multiple angles.
