Mitutoyo 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.

Mitutoyo Plus/Minus Dial Plunger-Style Variance Indicators with Calibration Certificate
These indicators come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They have a balanced dial with positive values on one side of the zero and negative values on the other side for comparative measurements of a part's tolerance against a reference measurement. 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.

Starrett Contact Point Sets for Plunger-Style Variance Indicators
These contact points are compatible with indicators that conform to AGD standards. Most plunger-style indicators are classified in AGD Groups 0, 1, 2, 3, or 4.
Radius and button contact points are best for use on flat surfaces.
Ball contact points are for measuring indentations. They can also be used to measure flat surfaces.
Bell contact points are used for measuring convex surfaces.
Tapered contact point can probe the bottom of a groove or narrow hole.
Cone contact points allow for precise positioning of the measuring tip. They are not for use on soft materials.
Shock-absorbing contact point protects against mechanical shock. A sudden impact will cause the tip to retract into the contact point’s body.
