Starrett Continuous Dial Plunger-Style Variance Indicators
For direct measurements, these indicators have a continuous dial numbered clockwise around the face. A spring-loaded plunger retracts and extends to measure objects. Rotate the dial face for viewing at multiple angles.
Jeweled bearings are more sensitive and wear resistant than plain bearings for a longer service life.

Starrett 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 Electronic 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. A spring-loaded plunger retracts and extends to measure objects. They have a zero-set button that lets you start measuring at any point.
Indicators with a rotating dial face can be viewed from multiple angles.
Indicators with SPC data output can be connected to a PC or data processor.
Indicators with go/no-go operation indicate when measurements fall outside your set tolerance.
Indicators with zero-position memory, also known as absolute (ABS) positioning, retain the measuring position when the indicator is off.
USB data cable (sold separately) connects indicators with SPC data output directly to your PC.

Starrett Electronic Plunger-Style Variance Indicators
View measurements on an easy-to-read LCD. A spring-loaded plunger retracts and extends to measure objects. These indicators have a zero-set button that lets you start measuring at any point. Rotate the dial face for viewing at multiple angles. SPC data output allows for connection to a computer or data processor.
Indicators with go/no-go operation indicate when measurements fall outside your set tolerance.
Indicators with zero-position memory, also known as absolute (ABS) positioning, retain the measuring position when the indicator is off.
USB data cable (sold separately) connects indicators with SPC data output directly to your PC.

Starrett Last Word Dial Lever-Style Variance Indicator Sets
Half of the measurement scale on the dial face is highlighted yellow to make measurements easier to read. Also known as test indicators, they have a lever-style contact point that pivots as it comes into contact with a surface and a balanced dial with positive values on one side and negative values on the other side. All have highly sensitive, wear-resistant jeweled bearings for a long service life. Rotate the dial face for viewing at multiple angles. The ratcheting contact point can be adjusted to various angles. Mount the indicator into lathe tool posts, height gauges, surface gauges, and other setups with the included accessories.

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.
