Mitutoyo 547-257A Electronic Depth Gage 0-8 in

Product Description

The MITUTOYO 547-257A is a stainless steel electronic depth gage with a measuring range of 0 to 8 inches (0 to 200 mm). It delivers an accuracy of 0.0003 inches and a resolution of 0.000050 inches, making it suitable for precision depth measurement in machining, inspection, and fabrication environments. The gage features a 2.5-inch base, a solid rod design with an included extension rod, and a built-in SPC output function for data logging. It runs on a single SR44 silver oxide battery, which is included. Machinists, quality control technicians, and precision fabricators are the primary users of this instrument.

The 547-257A is used in production and inspection settings where accurate depth readings are required on bores, slots, steps, and recesses. The inch/mm conversion function allows the user to switch between measurement systems without a separate tool. The automatic power on/off feature conserves battery life during intermittent use. The origin set and zero setting functions support fast setup at the point of measurement. This gage is appropriate for both shop-floor use and bench inspection work in light manufacturing and toolroom environments.

Compatibility

Designed as a standalone electronic depth gage for general precision measurement applications. No specific instrument system or replacement part compatibility is stated in the product data.

Installation Notes

No permanent installation is required. Before use, ensure the base and reference surface are clean and free of debris to maintain measurement accuracy. Battery replacement uses a standard SR44 silver oxide cell. Handle the gage in accordance with the manufacturer calibration and storage guidelines; this unit is shipped uncalibrated and should be verified against a traceable standard before use in a quality-critical application.
