The definitive bench micrometer, the Universal Supermicrometer (USM), offers the advantage of being two instruments in one, by providing the ability to measure both internal and external parts, gages or standards. Additionally, as a high precision, direct-reading metrology instrument, it is equally capable of checking critical components such as shafts, bores, O-rings, or just about any ID/OD part.
