Precisely measure shallow holes, slots, and recesses without any fine adjustments. Simply press these gauges against the bottom surface and push a button to measure. The LCD display makes measurements easy to read. Shaped to fit your palm, these gauges are also comfortable to hold and position. Store measurements on the gauge or wirelessly send them to a computer or data processor up to 30 ft. away using the built-in transmitter. With SPC data output, you can remotely analyze data and monitor measurements in real time.

A zero-set button lets you start measuring at any point. With zero-position memory, also known as absolute (ABS) positioning, these gauges retain their measuring position when the scale is off. To save battery life, they turn off after 20 minutes of inactivity.
