Dial Gauge, Lug Back, ISO Type

The Mitutoyo 2900A-10 is an analogue, EN ISO type, single turn dial indicator for small displacements. The measuring range is 0–0.08 mm with a division of 0.001 mm and a measuring range per revolution of 0.1 mm. The scale of the dial is 40–0–40 and the diameter of the dial is 57 mm (Series 2). The dial indicator has a lug back design and a diameter of 8 mm stem, allowing it to be mounted directly on stands and measuring jigs. The contact tip is made of carbide, with a thread of M2.5 × 0.45 mm. The construction is shockproof and jewel bearing mounted, and the dimensioning is marked in red with a 'dead zone' designated where accuracy is not guaranteed. The measuring force is typically ≤ 1.4 N.

The product is particularly suitable for very small displacement measurements and precision applications, such as measuring jigs and confined space measuring points, where a measuring range of 0.08 mm and a division of 0.001 mm per revolution are needed without requiring multiple revolution readings. Typical user groups include machine shops and metalworking industries, production and quality control units in manufacturing industries, and measurement and calibration laboratories measuring small deformations, clearances, and displacements via a measuring stand or fixed jig mounting.
