Product Overview
The Mitutoyo 1231AB-01 is an ANSI/AGD-type plunger dial gauge with a flat back design, 0.01 mm graduation and a 2.5 mm measuring range. It is designed for routine comparative measurement, runout inspection and machine or workpiece setup where a compact measuring range is required.
Made to American Gage Design dimensions, the 1231AB-01 is suitable for use with compatible inspection stands, holders, magnetic bases and fixtures. The flat-back configuration provides a clean, low-profile rear profile for stem-mounted setups, making it suitable for use with comparator stands, magnetic bases and custom fixtures.
The 2.5 mm measuring range provides practical travel for general shop-floor inspection and comparative measurement. Its mechanical movement is suited to day-to-day checking of dimensional deviations, alignment and runout during machining and inspection operations.
