Mitutoyo 543-312B-10 Electronic Bore Gage 0.5 in

Product Description

The MITUTOYO 543-312B-10 is an electronic bore gage designed for precise internal diameter measurement in small bores. It measures from 0.0000 to 0.5000 inches (0.00 to 12.7 mm) with an accuracy of 0.0001 inch (0.0030 mm) and a resolution of 0.00005 inch (0.001 mm). The gage includes a built-in indicator and outputs measurement data via SPC, making it suitable for integration with statistical process control systems. Machinists, quality control technicians, and precision measurement professionals are the primary users of this instrument.

This bore gage is suited for precision measurement tasks in manufacturing, machine shops, and quality assurance environments. It is used when verifying bore dimensions in components requiring tight tolerances, such as engine cylinders, hydraulic valve bodies, and precision-machined housings. The SPC data output makes it practical for high-volume inspection workflows where measurement data must be logged or analyzed electronically. The included indicator and battery allow for immediate use out of the box.

Key Features

• Measurement range of 0.0000 to 0.5000 inches (0.00 to 12.7 mm) for small-bore applications
• Accuracy of 0.0001 inch (0.0030 mm) for high-precision inspection
• Resolution of 0.00005 inch (0.001 mm) for fine measurement discrimination
• SPC data output for integration with statistical process control and data logging systems
• Includes indicator and one battery for ready-to-use deployment
• Gage depth of 4.75 mm for access into shallow bores

Compatibility

Designed for use as a precision internal measurement instrument in standard bore gaging applications where a 0.0000 to 0.5000 inch measurement range is required.

Installation Notes

This instrument is used by quality technicians and machinists and does not require permanent installation. Before use, verify the gage is zeroed correctly against a calibrated ring gage or master setting. Handle the contact points with care to avoid damage that would affect accuracy. Follow the manufacturer calibration interval recommendations to maintain measurement integrity.
