Economy 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 Continuous Dial Back Plunger-Style Variance Indicator Sets
The contact point is located on the back of this indicator, which allows the dial face to be read from above. It has a continuous dial numbered clockwise around the face for direct measurements. A rugged design with few moving parts and highly sensitive, wear-resistant jeweled bearings give it a longer service life than other indicators. Rotate the dial face for viewing at multiple angles.
Tip adapter lets you use AGD-standard contact points that have 4-48 threads with this indicator.
Hole attachment allows the indicator to take measurements inside holes and around obstructions.
Use the height gauge/tool post attachment to mount the indicator in your lathe tool post or the scriber clamp of your height gauge. Attach the indicator to the upright post with the swivel clamp.
Use the C-clamp with post to clamp the Starrett back plunger-style dial indicator to most thin, flat surfaces. Attach the indicator to the upright post with the swivel clamp.

Mitutoyo Continuous 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 continuous dial numbered clockwise around the face for direct measurements. 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.

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.
Indicators have a continuous dial numbered clockwise around the face for taking direct measurements. Rotate the dial face for viewing at multiple angles. All come with calibration certificates traceable to NIST that state the indicator and the granite base have passed a test for accuracy. They have jeweled bearings that are highly sensitive and wear resistant for a long service life.
Holders with jointed arm have a fine-adjustment knob for precise positioning of the indicator.
