Ari Industries T-50021 Thermocouple

The ARi Industries T-50021 Thermocouple is a mineral-insulated temperature sensor designed for harsh industrial environments, built in the USA by ARi Industries, a company established in 1952 and based in Addison, Illinois. ARi manufactures its own mineral-insulated cable and assembles thermocouples in‑house, enabling bendable sheaths, long lengths, and customized configurations to suit demanding processes. The product line covers a broad range of thermocouple types, including base‑metal and noble‑metal options, with calibrations traceable to National Institute of Standards and Technology (NIST) standards and in compliance with AMS2750 and ASTM E230 specifications. ARi’s high‑temperature offerings indicate support for thermocouple constructions capable of withstanding extreme conditions, with types such as B, R, S, C among the high‑temperature family; and the same engineering emphasis applies to standard and specialty assemblies used in furnaces, vacuum equipment, and industrial process monitoring. Each ARi thermocouple is manufactured in their Addison facility, with in‑house quality controls and calibration references, and the company advertises lead times for customized sensors (often around several weeks) to meet unique process requirements. While the T-50021 designation suggests a specific model in ARi’s catalog, ARi emphasizes tailored solutions, rapid quotes, and comprehensive support for sensor selection, installation, and maintenance across industries such as aerospace, energy, and metal processing.
