Spi 13-983-2 Electronic Bore Gage 1.4 to 2.4 in

Product Description

The SPI 13-983-2 is an electronic bore gage designed for precision inside-diameter measurement in machining, engine rebuilding, and quality-control applications. It covers a measuring range of 1.4 to 2.4 inches with a resolution of 0.00005 inches (0.001 mm) and an accuracy of 0.00025 inches. The unit includes an integrated digital indicator, supports both inch and metric readout, and provides data output for connection to SPC or data-logging equipment. It ships with six anvils, a spacer, and a fitted storage case, with batteries included for immediate use.

The 13-983-2 is suited for shop-floor and inspection-room use in automotive, aerospace, and general manufacturing environments. The 6-inch gage depth allows measurement of deeper bores such as engine cylinders, bushings, and bearing housings. Machinists, quality technicians, and toolroom personnel are the primary users. The inch/metric switching and data output make it compatible with modern quality workflows where dimensional data must be recorded or transferred digitally.

Compatibility

Designed as a direct-use precision bore gage for inside-diameter measurement applications requiring a range of 1.4 to 2.4 inches and a 6-inch gage depth; compatible with standard data output cables and SPC systems that accept digital gage input.

Installation Notes

Bore gages of this type are used by machinists and quality technicians and do not require installation in the traditional sense, but proper setup is critical for accurate readings. Zero the gage using a certified ring gage or master setting fixture before taking measurements. Keep the contact anvils clean and free of chips or debris, and allow the tool and workpiece to reach thermal equilibrium before measuring to avoid expansion errors. Store the unit in its fitted case when not in use to protect the anvils and indicator.
