The External Supermicrometer Model B is a bench-mounted direct-reading comparator designed for precision external diameter measurements. It features a carbide anvil surface, a measuring range of up to 10 inches (254 mm), and a direct reading range of 1 inch (25.4 mm). The instrument has an accuracy of 50 microinches (1.25 microns) and repeatability of 20 microinches (0.5 micron), with analog meter resolution of 10 microinches (0.3 micron). It requires 110/120V at 2A/60Hz or 220/240V at 1A/50Hz, and has a bench space requirement of 25.5 x 11.5 inches (65 x 30 cm). The unit weighs approximately 150 lbs (68 kg) and has a bed diameter of 3.75 inches (95 mm). The tailstock features a zero-center meter with graduations of 20 microinches per division for direct reading and 10 microinches per division for comparator reading.
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.
