Fowler 54-554-624-0 Inside Electronic Caliper Gage

Product Description

The FOWLER 54-554-624-0 is an inside electronic caliper gage designed to measure internal dimensions with high accuracy in a compact measurement range. The gage covers a measurement range of 0.79 to 1.6 inches and delivers a resolution of 0.0005 inch with an accuracy of 0.0008 inch. Powered by a 357 battery and equipped with a digital readout, it provides fast, repeatable internal measurements. The unit ships with a protective case. Machinists, metrology technicians, and precision measurement professionals are the primary users of this instrument.

The 54-554-624-0 is suited for internal bore and groove measurements in manufacturing, machine shop, and quality control environments. It is appropriate for use where a standard caliper cannot access internal features, making it a practical tool for inspecting bored holes, cylinder bores, and similar internal geometries. The 0.79 to 1.6 inch range covers a wide variety of small-to-medium internal features encountered in both production and inspection settings.
