The Tesa Interapid 74.111371 (model 312B-2) is a Swiss-made lever-type dial test indicator manufactured by TESA Technology, a Hexagon Manufacturing Intelligence brand, and is supplied new in the original molded plastic case with declaration of conformity and traceability documentation. The indicator reads in inch units with a 0.0005 in graduation, a total measuring range of 0.030 in, and a bezel diameter of 37.5 mm (approximately 1-1/2 in); the dovetail-style swivel clamp accepts a 3/8 in stem for mounting to magnetic bases, indicator holders, and transfer stands. Maximum deviation over a full rotation is 0.0004 in and repeatability is 0.00012 in per the manufacturer's published specification sheet included with the unit. The ruby-tipped contact point is set in a pivoting lever arm adjustable to multiple angular positions, and the balanced white dial face carries a mid-scale zero suitable for plus/minus runout, concentricity, flatness, and surface comparison work on precision machining and inspection fixtures.
