Mitutoyo 209-932 Outside Electronic Caliper Gage

Product Description

The MITUTOYO 209-932 is an outside electronic caliper gage designed to measure external groove dimensions with high resolution and digital readout. It uses ball-to-ball contact points with a tip diameter of 1.5 mm to seat accurately inside narrow external grooves. The gage measures from 0 to 0.78 inches (0 to 20 mm) with a resolution of 0.0005 inch (0.01 mm) and an accuracy of 0.0015 inch (0.03 mm). Data output capability allows readings to be sent to a connected device or SPC system. Powered by two AAA batteries, this instrument is suited for production floor and inspection environments where repeatable external groove measurement is required.

This gage is used for external groove measurement applications in manufacturing, machining, and precision inspection settings. The ball-to-ball contact geometry makes it well-suited for measuring snap ring grooves, retaining ring grooves, and similar external features on turned or machined components. It is typically deployed by machinists, quality control technicians, and metrology professionals working to tight dimensional tolerances. The 80 mm groove depth capacity and 3.2 mm leg length accommodate a range of part sizes common in general machining and component inspection work.

Compatibility

Designed as an OEM-style outside electronic caliper gage for external groove measurement; suitable for use on machined components where ball-to-ball contact measurement of grooves up to 0.78 inches is required.

Installation Notes

This instrument is used by machinists and quality technicians and requires no permanent installation. Before use, verify battery charge and zero the gage per standard metrology practice. Keep contact points clean and free of debris to maintain accuracy. Handle with care to avoid dropping, which can affect calibration and contact point integrity.
