Fowler 54-554-725-0 Outside Electronic Caliper Gage

Product Description

The FOWLER 54-554-725-0 is an outside electronic caliper gage designed for precise external measurement of workpieces ranging from 1.2 to 2 inches. Built for metrology and quality-control applications, it delivers a resolution of 0.0005 inches and an accuracy of 0.0008 inches (0.0200 mm). The gage is powered by a 357 battery and includes a protective case for storage and transport. Machinists, calibration technicians, and quality-control inspectors will find this instrument appropriate for high-precision dimensional verification on the shop floor or in an inspection environment.

This caliper gage is intended for external measurement tasks in manufacturing, machine shops, and inspection departments. It is suited for measuring outside diameters, widths, and thickness dimensions where tight tolerances must be verified. The 80 mm leg length and 0.75-inch tip diameter make it effective for a range of part geometries. No data output port is included, so readings are recorded manually. The unit ships individually and is ready for immediate use out of the box.

Key Features

• Measurement range of 1.2 to 2 inches for outside dimensions
• Resolution of 0.0005 inches for fine dimensional readings
• Accuracy of 0.0008 inches (0.0200 mm) for reliable inspection results
• 80 mm leg length with a 0.75-inch tip diameter for varied part geometry access
• Runs on a standard 357 battery - a common, easy-to-source cell
• Includes a protective carrying case for storage and transport

Compatibility

Designed as a standalone outside electronic caliper gage for general external-measurement applications in machine shop, manufacturing, and quality-control environments.

Installation Notes

This instrument requires no permanent installation. Calibration technicians and machinists should zero the gage before use and verify against a known reference standard. Handle contact tips with care to avoid nicking or contaminating the measuring surfaces, as surface damage directly affects accuracy. Replace the 357 battery when the low-battery indicator activates to maintain measurement integrity.
