McMaster 6549N11 Electronic Plunger Variance Indicator with Flexible-Arm Magnetic-Base Holder, Forward Count

Bend and flex the arm of the base to position your indicator—these holders have ball-and-socket segments that lock in place with a lever. The base is magnetic and has a V-groove on the bottom for a solid mount on flat and curved metal surfaces. Flip a switch to release the magnet.

A spring-loaded plunger extends and retracts from the indicator to take measurements. The measurements display on an easy-to-read LCD screen. Press the zero-set button to start measuring at any point. They have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the indicator is off.

All can send data to your computer using a USB cord (sold separately). They have SPC data output to wirelessly transfer your measurement data to your device with the push of a button.

Wireless Data Transmitter/Receiver Set (45 ft. Wireless Range)—If you’d rather transmit SPC data wirelessly to your computer, add a data transmitter/receiver set.
