Mitutoyo 209-936 Inside Electronic Caliper Gage

Product Description

The MITUTOYO 209-936 is a ball-to-ball contact inside electronic caliper gage designed for precise internal groove and bore measurements. It measures ranges from 0.39 to 1.18 inches and delivers 0.0005-inch resolution with 0.0015-inch accuracy, making it suitable for tight-tolerance inspection work. The ball contact design allows the gage to seat cleanly inside grooves as narrow as 0.0472 inches and as deep as 0.2047 inches. Built-in data output supports direct connection to SPC data collection systems. This tool is used by machinists, quality control technicians, and precision measurement professionals in manufacturing and inspection environments.

The 209-936 is suited for internal groove inspection on small bores, retaining ring grooves, O-ring grooves, and similar features where access is restricted. The 0.0394-inch tip diameter and 3.3465-inch leg length allow the gage to reach into confined spaces without contact interference. It is appropriate for use on production floors, inspection benches, and field measurement applications where electronic readout and data logging are required.

Compatibility

Designed as an OEM-style electronic caliper gage for internal groove and bore measurement applications requiring ball-to-ball contact geometry and electronic data output.

Installation Notes

This gage is a handheld precision measurement instrument and does not require permanent installation. Calibrate against a known standard before use per your facility quality procedures. Handle contact points with care to avoid damage that would affect measurement accuracy. Install the included AA battery before first use and replace when the low-battery indicator activates.
