IET Labs, IncFounded in 1976, IET Labs manufactures precision electrical test and measurement equipment, with a particular focus on metrology standards and meters for resistance, capacitance and inductance. The U.S. manufacturer also preserves the GenRad and esi instrument lines acquired in 2000 and 2006, while providing calibration and repair through its ISO-17025-accredited laboratory. IET says 98% of its products are manufactured in the United States.ROSLYN HEIGHTS, NY
United Instruments, IncSince its founding in 1997, United Instruments has built its identity around in-house engineering and calibration work for utility and industrial customers. Owner Mark Grigoraki brought the company the rights to manufacture the Precision Low Pressure Calibration System in 1998, and United Instruments still performs its manufacturing and calibration work in the USA for metrology labs and major corporations.WESTBURY, NY
Lake Shore Cryotronics, IncFrom its Westerville manufacturing operations, Lake Shore Cryotronics makes precision sensors, instruments, and systems for measuring and controlling cryogenic temperatures and magnetic fields. Its equipment supports research and testing in areas ranging from superconductivity to electronic devices, with the company marking 50 years in business in 2018. Lake Shore achieved ISO 9001 certification in 1998 and also holds ISO/IEC 17025 accreditation for specified calibrations performed in Westerville.WESTERVILLE, OH
Morgan Precision InstrumentsFounded as Morgan Tool and Die in 1938, Morgan Precision Instruments carries Akron toolmaker Otello “Oty” Capanna’s conviction that “perfection is not a little thing.” The company became Morgan Precision Instruments in 1999 and brings that precision-gauge heritage to custom manufacturing work for customers in industries ranging from automotive to medical. ISO/IEC 17025 accreditation in calibration and dimensional measurement underscores the measurement traceability at the heart of its work.AKRON, OH
