The durable, analog design of these gauges holds up in machine and toolmaking shops where you regularly need to measure and mark material before cutting. Because they’re analog, they’re best when you don’t need to transfer data. In addition to their dial, they have two mechanical counters that display measurements—one counts up, the other counts down. Twist the hand wheel to adjust the height up and down the column. For repeat marking, set the attached scriber at a specific height. Use the zero-set button to start measuring at any point.
