Fowler 54-125-777-0 Electronic Depth Gage 0-22 in

Product Description

The FOWLER 54-125-777-0 is an electronic digital depth gage designed for precision measurement across a range of 0 to 22 inches. Built from alloy steel, it delivers an accuracy of 0.0008 inches and a resolution of 0.0005 inches, making it suitable for demanding inspection and layout tasks in machine shops, fabrication environments, and field service. The 4-inch base provides stable seating on workpiece surfaces, and the included set of six interchangeable rods covers depths from 1 through 6 inches in individual increments. Machinists, tool-and-die technicians, and precision measurement professionals are the primary users of this instrument.

This depth gage is suited for production inspection, quality control, and layout work on machined components, castings, and fabricated assemblies. The direct inch/metric conversion function allows seamless switching between measurement systems without recalculating. The hold feature freezes the displayed reading for easy recording, and the relative/absolute measuring mode supports comparative measurement against a reference value. Six measuring rods are included, each 1 inch long and stackable, allowing the gage to reach depths from 1 inch up to the full 22-inch range.

Installation Notes

This instrument requires no installation but should be handled and stored according to standard metrology practices. Before use, verify the base seating surface is clean and free of burrs or debris that could affect measurement accuracy. Zero the gage on a known flat reference surface before beginning measurements. Data output is not supported on this model, so readings should be recorded manually or via the hold feature.
