Interapid 74.111372 312B-3 0.0008in 0.0001in Lever Dial Test Indicator

The Interapid 312B-3 (catalog ref 74.111372) is a Swiss-made horizontal lever-type dial test indicator manufactured by TESA/Hexagon, new in original plastic case with instruction manual and declaration of conformity with traceability. The dial reads 0–4–0 balanced scale with a resolution of 0.0001 in and a total travel of 0.0008 in (±0.0004 in per side), with a 1-3/8 in (35 mm) dial face; the indicator body mounts via a standard 3/8 in dovetail shank and the stylus is field-adjustable to multiple angular positions using the knurled clamp screws on the pivot arm. The ruby-tipped stylus and jeweled movement are consistent with Interapid's published specification for the 312 series; the balanced white dial with 80 graduations, dual needle (one per half-travel), and bezel-set zero make it well-suited for surface runout, TIR, and part setup on surface plates, CMMs, sine plates, and magnetic base setups. Box label confirms part string INTERAPID312.016.0001 D1-1/2, cross-referencing TESA item 074.111372, Qty 1, with UKCA and Prop 65 compliance labels affixed.
