Product Overview
The Mitutoyo 2990A-10 is an ISO-type Series 2 plunger dial gauge with a back plunger design, one-revolution dial, 0.001 inch graduation, and 0.1 inch measuring range. It is designed for routine comparative checks, runout inspection, and set-up work where a practical resolution and compact travel are required.
Its ISO-type design dimensions make it suitable for inspection setups built around this pattern. Check that your stands, holders, and fixtures are compatible with the ISO-type design before installation.
The back plunger design positions the plunger at the rear of the gauge, perpendicular to the dial. This makes the gauge convenient to mount in confined spaces while keeping the dial face visible to the operator. The one-revolution dial displays the full 0.1 inch measuring range in a single turn, helping simplify readings and reduce the risk of miscounting revolutions.
The mechanical movement is designed for dependable day-to-day shop-floor use. Need a different resolution or shorter travel? The Mitutoyo 2991A-10 offers 0.0001 inch graduation over a 0.008 inch range.
