Precision Weighted-Base Indicator Holders
These holders come with a certificate of accuracy traceable to NIST stating that the granite base has passed a test for surface accuracy. The extremely tight flatness tolerances of the granite allow for nearly frictionless workpiece movement and provide an accurate reference plane for inspection work.
Holders with jointed arm have a fine-adjustment knob for precise positioning.

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.
