    Side View

    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 Bearing—Jeweled bearings are more sensitive and wear resistant than plain bearings for a longer service life.
