Mitutoyo 2046AB Dial Drop Indicator 10mm 0.01mm Graduation

Product Description

The MITUTOYO 2046AB is a dial drop indicator designed for precision dimensional measurement in industrial and trade settings. It covers a 10mm measurement range with a 0.01mm graduation and delivers an accuracy of 0.013mm, making it suitable for close-tolerance inspection work. The 57mm white dial provides a clear, easy-to-read display, and the crystal is glare-free and scratch-resistant for reliable use in shop environments. A revolution counter tracks full 1mm-per-revolution cycles across the full range. Licensed metrologists, machinists, and calibration technicians are the primary users of this instrument.

This dial drop indicator is used in precision measurement applications including surface plate inspection, runout measurement, and fixture alignment. It is well suited for quality control workflows in machine shops, manufacturing facilities, and tool rooms. The flat back style allows secure mounting in standard indicator holders and magnetic bases. The M2.5 x 0.45 thread and 8mm stem diameter fit common dovetail and post-style holders used across the trade. Compliance with ISO and JIS standards makes this indicator appropriate for certified inspection environments.

Installation Notes

Dial drop indicators are installed by machinists, metrologists, and quality technicians using indicator holders or magnetic base assemblies. Secure the stem firmly in the holder before zeroing the dial to prevent shifting during measurement. Avoid applying lateral force to the spindle, as this can introduce measurement error or cause internal damage. Handle the instrument carefully and store it protected from impact and contamination when not in use.
