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.

Economy Electronic Plunger-Style Variance Indicators with Magnetic-Base Holder
A magnetic base provides a solid mount on metal surfaces. It has a V-grooved bottom for mounting on flat and curved surfaces and a magnetic release switch for easy setups. Use the fine-adjustment knob for precise positioning of the holder’s arm.
The indicator has a spring-loaded plunger that retracts and extends to measure objects. It has zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the indicator is off. A zero-set button lets you start measuring at any point, and a go/no-go operation indicates when measurements fall outside your set tolerance.
