Fowler 54-554-622-0 Inside Electronic Caliper Gage

Product Description

The FOWLER 54-554-622-0 is an inside electronic caliper gage designed for precise internal measurement of bores, slots, and grooves. It covers a measurement range of 0.2 to 1 inch with a resolution of 0.0005 inches and an accuracy of 0.0008 inches, making it suitable for close-tolerance inspection work. The 2-inch leg length supports access to typical internal features encountered in machining, maintenance, and fabrication environments. Machinists, toolroom technicians, and quality control personnel use this gage for fast, repeatable inside-diameter checks without the setup time required by bore gauges or telescoping tools.

This inside caliper gage is suited for shop floor and bench inspection applications where internal dimensions must be verified quickly. Typical use cases include checking cylinder bores, valve seats, housing IDs, and machined slots in both production and MRO settings. The electronic readout eliminates the interpretation error common with vernier-style gages. It ships with a protective case, keeping the measuring faces and leg tips protected during storage and transport between jobs.

Key Features

• Measurement range of 0.2 to 1 inch covers common small-bore internal dimensions
• Resolution of 0.0005 inches supports close-tolerance inspection tasks
• Accuracy rated at 0.0008 inches for reliable, repeatable readings
• 2-inch leg length provides reach into standard internal features
• Electronic display reduces reading error versus vernier scales
• Includes protective carrying case for storage and transport

Compatibility

Designed as a general-purpose inside electronic caliper gage for internal measurement applications in machining, maintenance, and quality inspection environments.

Installation Notes

This is a precision measurement instrument, not an installed component. Handle measuring faces and leg tips with care to avoid nicks or burrs that affect accuracy. Zero the gage before use and allow the instrument to reach ambient temperature if moved from a cold environment. Store in the included case when not in use to protect the contact surfaces.
