Marathon Monitors and Control Systems (Beijing) Corp., a wholly owned subsidiary of Marathon Multinational Industries (MMI), has begun manufacturing, marketing and distribution of its "Carbonking" oxygen sensor for atmosphere heat-treating applications. The Carbonking sensors can be used in all heat-treat, carbon-controlled processes, including carburizing, carbonitriding, sintering and annealing.

This series of sensors, currently manufactured only in China, is derived from the designs of Marathon-Beijing's sister company, Marathon Sensors Inc. (Cincinnati, Ohio). In addition to sales within China, the Carbonking probe is also available for export throughout Asia.
