Mitutoyo 547-217A Digital Depth Gauge 0-8 in 0.01mm

Product Description

The MITUTOYO 547-217A is a digital depth gauge designed for precise depth measurement in machining, inspection, and fabrication environments. It features a resolution of 0.01mm (0.0005 inches) and covers a measurement range of 0 to 8 inches, making it suitable for a wide variety of depth-measurement tasks. The gauge uses an IDC (Inch/mm Digital Counter) display format and incorporates a solid rod for consistent, repeatable contact. Weighing 1.5 pounds, it is built for bench and field use by machinists, quality control technicians, tool and die makers, and precision measurement professionals.

This depth gauge is suited for use in manufacturing, toolroom, and inspection settings where accurate depth readings are required on bores, steps, slots, and recessed features. The 2.5-inch base provides stable seating on workpiece surfaces during measurement. Its dual-unit readout supports both metric and inch-based workflows, allowing technicians to work across different specification standards without conversion tools.

Key Features

• Resolution of 0.01mm (0.0005 inches) for fine measurement accuracy
• Measurement range of 0 to 8 inches (0 to 200mm)
• 2.5-inch base length with a flatness of 0.0002 inches for stable, accurate seating
• Solid rod type, 4 inches in length, for rigid contact and consistent readings
• Measuring force range of 0 to 1.5 N to minimize workpiece deflection
• Overall height of 3.5 inches for ergonomic handling at the bench or in the field

Compatibility

Designed as a direct-use digital depth gauge for general precision measurement applications in toolroom, manufacturing, and inspection environments where 0 to 8-inch depth range and 0.01mm resolution are required.

Installation Notes

This instrument is handled and used by machinists and quality control technicians rather than installed in a system. Before use, ensure the base and rod contact faces are clean and free of debris to prevent measurement error. Zero the gauge on a known flat reference surface prior to taking measurements. Do not apply lateral force to the rod during measurement, as this can affect accuracy and damage the instrument.
