Mitutoyo 2971AB | One-Revolution Dial Indicator | 0.5 mm Range, 0.01 mm Graduation, Flat Back
Part No. 2971AB | Range 0.5 mm | Graduation 0.01 mm
Product Overview
The Mitutoyo 2971AB is an ISO-type Series 2 dial gauge with a flat back design, one-revolution dial, 0.01 mm graduation, and 0.5 mm measuring range. It is designed for routine comparative checks, runout inspection, and setup work on the shop floor.
The gauge follows ISO-type design dimensions, so existing stands and holders should be checked for compatibility before installation. With 0.01 mm graduation over 0.5 mm of travel, it provides practical resolution for inspection applications where a compact measuring range is sufficient.
The flat back provides a clean, low-profile rear profile for applications where the gauge is mounted by its stem in a magnetic base, comparator stand, or custom fixture. Its one-revolution dial displays the full 0.5 mm range within a single pointer revolution, simplifying readings during repetitive inspection work. The mechanical movement is suited to regular day-to-day workshop use.
For a different measuring range, the Mitutoyo 2972TB is listed with a 0.01 mm graduation and 1 mm range.
