Product Overview
The Mitutoyo 2991A-10 is an ANSI/AGD Series 2 dial gauge with a back plunger design, one-revolution dial, 0.0001 inch graduation and a 0.008 inch measuring range. It is designed for high-resolution comparative inspection where very small deviations need to be identified.
Built to ANSI/AGD dimensions, the gauge is suitable for use with common stands, fixtures and holders found in inspection rooms and machine shops. Its back plunger places the measuring plunger at the rear of the gauge, perpendicular to the dial, making it suitable for mounting in confined spaces while keeping the dial face visible to the operator.
The one-revolution dial displays the complete 0.008 inch measuring range in a single pointer revolution, helping simplify readings and reducing the possibility of revolution-counting errors. The gauge features shockproof construction, a balanced dial and a carbide-tipped contact point for dependable workshop use.
For a different resolution and longer travel, consider the Mitutoyo 2961T, which provides 0.0005 inch graduation over a 0.04 inch range.
