Mitutoyo 547-218A Electronic Depth Gage 8 Inch

Product Description

The MITUTOYO 547-218A is an electronic depth gage designed for precise depth, step, and recess measurements in machining, fabrication, and inspection environments. It uses a solid rod design with a carbide-tipped, hardened and lapped base that delivers a high degree of flatness for accurate seating on workpiece surfaces. The gage measures from 0 to 8 inches (0 to 200 mm) with a resolution of 0.0005 inch (0.01 mm) and accuracy of plus or minus 0.001 inch (0.0254 mm). Weighing 1.5 pounds, it is compact enough for bench or field use. Machinists, tool-and-die workers, and quality control technicians are the primary users of this instrument.

The 547-218A suits precision measurement tasks in machine shops, manufacturing facilities, and quality inspection departments. It is appropriate for measuring slot depths, counterbore depths, and similar features on machined or fabricated parts. The 4-inch base provides stable contact across a range of workpiece geometries. An origin-point memory function retains the set reference for the full life of the battery, which supports consistent comparative measurement across a production run.

Compatibility

Designed as a standard electronic depth gage for general precision measurement applications. No specific compatible equipment or replacement fitment is stated by the manufacturer for this model.

Installation Notes

Depth gages of this type are calibrated and used by machinists or metrology technicians and do not require permanent installation. Before use, clean and inspect the base seating surface and the workpiece reference surface to remove debris that could affect accuracy. Zero or set the origin point on a known reference surface before taking measurements. This unit is not calibrated from the factory; users requiring traceable calibration should arrange third-party calibration prior to use in a quality-controlled environment.
