Pratt & Whitney's Supermicrometer Model C is the most popular pin gage measuring instrument in industry. The External Supermicrometer is the most widely used bench micrometer that can measure just about any manufactured precision part or gage such as pins, plugs, and all types of threads including: API, NPT, NPTF, Dryseal, BSPP, BSPT, UN (Unified), M Profile (Metric), ACME, Buttress, UTS, UNC, UNF, UNEF, UNS, BSW (Whitworth), BA, BSC, BSF, BSP. The External Supermicrometer Model C is also the industry standard, 3-Wire Thread Measuring System.
Pratt & Whitney also offers a number of machines suitable for calibrating pin gauges:
1. Labmaster Universal (Model 175, 1000M, 1000A)
2. Laser Measuring Machine
3. Labmicrometer (Model 900, 1600)
4. Digital Measuring Machine
5. Universal Supermicrometer (Model 501, 504)
