ARi Industries, Inc.

ARi Industries began as a manufacturer and supplier of quality thermal management products for a world of industrial and commercial process applications.

We began in 1952 as Aero Research Instruments, in Chicago Illinois. ARi was among the first pioneering companies to manufacture mineral insulated cable to improve product performance and reliability. Over the decades, we’ve refined and improved that technology, as it remains the heart of our products to this day.

ARi is recognized as the industry leader of metal-sheathed, mineral insulated thermocouple cable. All our standard AerOpak^® thermocouple cable is supplied with high-purity MgO (magnesium Oxide) insulation and accuracies per ASTM E-230 limits of error. We main large inventories of finished cable and ARi also specializes in custom thermocouple, conductor and heater cables to meet virtually any application requirement of temperature, environment or process conditions.
