Mitutoyo 571-261-20 Electronic Depth Gage 0-6 in

Product Description

The MITUTOYO 571-261-20 is a stainless steel electronic depth gage with a measuring range of 0 to 6 inches (0 to 150 mm). It is designed for precision depth measurement of slots, holes, shoulders, and stepped surfaces in machining, fabrication, and quality-control environments. The gage delivers a resolution of 0.0005 inches (0.01 mm) and an accuracy of 0.001 inches (0.02 mm), making it suitable for applications that demand close tolerance verification. The 3.937-inch (100 mm) base provides a stable reference surface across a wide range of workpiece geometries. Licensed machinists, tool-and-die technicians, and QC inspectors are the primary users of this instrument.

This depth gage is well suited for use in machine shops, manufacturing facilities, and inspection departments handling both inch and metric dimensioned parts. The IP67 water-resistance rating makes it appropriate for use in wet or coolant-exposed shop environments. The built-in SPC output function allows connection to statistical process control systems for in-process measurement data collection. A single SR44 battery is included, and the automatic power on/off feature conserves battery life during intermittent use.

Installation Notes

This instrument requires no permanent installation. Before use, ensure the base and blade seating surfaces are clean and free of burrs or debris that could affect reference accuracy. Zero the gage on a known flat reference surface before taking measurements. Calibration should be verified periodically per your facility quality plan or applicable metrology standards.
