Location:
Marathon Sensors Inc. is headquartered in West Chester, Ohio, USA, and has representatives, agents, and distributors around the world.

Corporate History:
Marathon Sensors Inc., formerly Marathon Monitors, was established in 1982 as a manufacturer of Oxygen Probes. In the beginning, the company focused exclusively on the heat-treat industry, designing and manufacturing probes, and later instrumentation and control systems, that met the needs of this demanding environment. As the company grew and expanded, markets in Europe and the Pacific Rim were established in 1985. 

In 1995, the company expanded its product line and market coverage when it acquired the technology rights of Zircoa (division of Corning). This acquisition of Oxygen sensors and instruments for the measurement and control of O2 in the combustion process, allowed MSI to expand into the Refinery/Petrochemical, Fossil Fuel Power, Glass and Ceramics, Incineration and the Steel Reheat industries.

Quality Certifications: ISO 9001:2000 Registered, CE marked for instruments and sensors, TÜV (Germany) approved for Oxygen probes.
