For more than 40 years, Thermo Gauge Instruments has built precision blackbody calibration systems, including rapid-response graphite tube furnaces designed to approximate Max Planck’s ideal for thermal-radiation measurement. Its in-house machine shop supports custom builds and long-term service, with every blackbody system backed by original or upgraded replacement parts; many units remain in use today. Thermo Gauge’s systems are used by standards and calibration laboratories worldwide.
The Bionetics Corporation (Bionetics C.E.S.G.; formerly Intek, Inc.)Since Intek’s founding in 1976, the central Ohio operation now known as Bionetics C.E.S.G. has made precision thermal flow instruments and condenser-monitoring systems, while developing custom measurement solutions for demanding industrial, nuclear and aerospace applications. The Bionetics Corporation acquired Intek’s assets and retained key staff to carry forward the Rheotherm® and RheoVac® product lines, including instruments that have flown on NASA manned spacecraft and supported nuclear plants measuring radiation-hardened flows. Products are manufactured and calibrated in Ohio under an ISO 9001:2015-certified quality program.WESTERVILLE, OH
InTest Thermal SolutionsInTest Thermal Solutions designs and manufactures precision temperature-control systems for thermal testing, process cooling, and biomedical cold storage. Its four brands build on more than 50 years of experience, with the company having delivered over 100,000 controlled heating and cooling systems worldwide. In-house engineering and manufacturing support both standard and custom systems, and its quality program is built on ISO 9001.BROOKLYN, NY
femto-TECH, INCKnown in radiation measurement since 1986, femto-TECH, INC. is a Carlisle, Ohio manufacturer whose U.S.-made instruments have become fixtures in professional and government testing. The company’s long-lived equipment is still sent back for calibration decades after manufacture, while its staff also develops specialized monitoring systems for national laboratories and nuclear-reactor applications.FRANKLIN, OH
Cleveland Electric LaboratoriesFounded in 1920 as a repair service for railroad and Cleveland industries, family-owned Cleveland Electric Laboratories now makes custom high-temperature thermocouples and industrial sensors for demanding temperature, pressure, and strain measurements. Based in Twinsburg, the company also operates an ISO/IEC 17025-accredited calibration laboratory capable of certifying temperatures from -320°F to 2800°F. Its work spans built-to-order sensing solutions, turbine-engine instrumentation, and complex small-batch machining, with quality systems certified to ISO 9001 and AS9100D.TWINSBURG, OH
