Starrett Continuous Dial Back Plunger-Style Variance Indicators
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. The included tip adapter lets you use AGD-standard contact points that have 4-48 threads.

Starrett Continuous Dial Back Plunger-Style
Variance Indicators with Calibration Certificate
This indicator comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy. The contact point is located on the back, 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. The included tip adapter lets you use AGD-standard contact points that have 4-48 threads.
