    With Rigid Arm

    With Jointed Arm

    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.
    Jointed Arm—Holders with jointed arm have a fine-adjustment knob for precise positioning.

    Dial Plunger Variance Indicators with Precision Weighted-Base Holder

    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.
