The External Supermicrometer Model B is a bench-mounted measuring instrument designed for direct-reading comparison of external dimensions such as pins, plugs, and threads. It features a carbide anvil surface, a direct reading range of 1 inch (25.4 mm), and a total measuring range of up to 10 inches (254 mm). The instrument has a resolution of 10 microinches (0.3 micron) on its analog meter and a repeatability of 20 microinches (0.5 micron), with an accuracy of 50 microinches (1.25 microns). It requires 110/120V at 2A 60Hz or 220/240V at 1A 50Hz. The unit weighs approximately 150 lbs (68 kg) and has a bench footprint of 25.5 x 11.5 inches (65 x 30 cm).
If you're looking for a direct-reading vernier-style bench micrometer and an electronic size comparator for use in the calibration laboratory or on the production floor, look no further, the second-generation External Supermicrometer Model B provides durability, speed of measurement, and range of applications. The Supermicrometer is the most popular bench micrometer in the world that can measure just about any manufactured precision OD part, turned part, or gages such as pins, plugs, and threads including API, NPT, NPTF, BSPP, BSPT, UN (Unified), M Profile (Metric), ACME, Buttress, UTS, UNC, UNF, UNEF, UNS, BSW (Whitworth), BA, BSC, BSF, BSP, to name a few.
