The Interapid 74.111370 is a new, Swiss-made horizontal dial test indicator manufactured by TESA Technology under the Interapid brand, model 312B-1, with a measuring range of 0–0.060 in and a graduation of 0.0005 in per division. The indicator features a balanced 0-15-0 dial face with a 1-1/2 in (38 mm) dial diameter, a dovetail-mount horizontal contact point arm, and a vertical stem for standard indicator holder clamping. Designed for high-precision runout, alignment, and surface measurement tasks on surface plates, machine tool setups, and inspection fixtures, this indicator is traceable to Swiss metrology standards and arrives in the original TESA plastic carrying case with spare contact points. The part number suffix 74.111370 corresponds to TESA's catalog identifier for the inch-reading 312B-1 horizontal model with 0.0005 in graduation and 1-1/2 in dial, as confirmed by the box label reading 'INTERAPID312 .06 .0005 D1-1/2'.
