Measure depths up to 8” by combining multiple extension rods. These gauges are three times more accurate than our standard electronic depth gauges with extension rods. They have an LCD screen that makes measurements easy to read. Often used during manufacturing, they help make sure drilled holes and machined slots meet design specifications and fit in assemblies. Simply press them against the bottom of a hole or slot and push a button to measure—no fine adjustments needed. Or start measuring at any point by pushing the zero-set button. These gauges have built-in memory to store measurements and an SPC data output. Connect them to a computer or data processor to analyze data and monitor measurements in real time.

To save battery power, these gauges automatically turn off after 20 minutes of inactivity. With zero-position memory, also known as absolute (ABS) positioning, they retain their measuring position when they’re turned off.
