Fowler 54-554-730-0 Inside Electronic Caliper Gage

Product Description

The FOWLER 54-554-730-0 is an inside electronic caliper gage designed for measuring internal dimensions such as bores, slots, and grooves. It covers a measurement range from 12.70 mm (0.5 inch) up to 150 mm (6 inches) with a resolution of 0.01 inch (0.1 mm), allowing precise readings in both inch and millimeter modes. The contact points are radius-to-radius style, suited for internal groove measurement. At 0.4 pounds, this gage is lightweight and practical for bench or floor use. It is powered by a single CR2032 battery, which is included. Machinists, quality control technicians, and tool room professionals install and operate this gage in production and inspection environments.

This inside caliper gage is intended for internal measurement applications where standard jaw-type calipers cannot reach, including narrow grooves and small-bore features. It is appropriate for use in precision machining, automotive, aerospace, and general manufacturing inspection settings. The 0.12 inch groove width capability makes it compatible with measuring tight internal slots and snap-ring grooves. It suits both shop floor and metrology lab environments where repeatable electronic readout is required.

Installation Notes

This gage requires no installation in the traditional sense and is operated by a qualified machinist or quality technician. Before use, zero the gage at the minimum reference point according to the manufacturer calibration procedure. Keep contact points clean and free of chips or coolant to maintain accuracy. Inspect the battery compartment for proper CR2032 seating before each use session.
