Mitutoyo 2904 Dial Indicator 0.001" x 1.000" 100-0 Reverse Reading Custom Tip

Mitutoyo 2904 Dial Indicator 0.001" x 1.000" 100-0 Reverse Reading Custom Tip

The Mitutoyo 2904 is a mechanical dial indicator with a 0.001" graduation and a 1.000" measuring range. It features a 100-0 reverse-reading dial face, which reads from 100 down to 0 as the spindle advances — useful in setups where reverse-direction reading is required. This unit is fitted with a custom contact tip; the standard Mitutoyo tip is not included.

Applications

Dial indicators like the Mitutoyo 2904 are standard precision measurement tools in machine shops, toolrooms, and quality control environments. They are used to check runout, flatness, parallelism, and part alignment on mills, lathes, surface plates, and CMM setups. The reverse-reading (100-0) dial is particularly suited to applications where the operator approaches a target value from above — common in depth measurement, press-fit inspection, and certain fixture-checking routines. Mitutoyo dial indicators are a long-established benchmark in precision metrology and remain in active everyday use across manufacturing and inspection settings worldwide.
