The Marathon Oxygen Probe from the USA is widely recognized in the global industrial sector, setting the industry standard. The operating temperature range is 700-1100℃ (1292-2012℉). It features a RA330 alloy sheath for durability and long-term stability in working temperatures, with excellent corrosion resistance, and can be inserted into the furnace for 10" (254mm). Available in various sizes, including 20" (600mm), 30" (800mm), 40" (1000mm), 47" (1200mm), to accommodate different furnace types or installation methods. The installation size is 1.05" (26.67mm) NPT pipe thread, offering good sealing. The built-in thermocouple types include "K," "S," and "R" types. The carbon potential control range is 0-1.50% CP. The carbon potential measurement accuracy is high at 0.01% CP. The oxygen potential measurement accuracy is less than 1mv. Low internal resistance, less than 1K ohm at 900℃. High sensitivity with a quick response time of less than 1 second. Consistent probe performance with rapid carbon burn-back time. Typically, the oxygen probe has a lifespan of over 18 months under normal conditions. Easy installation and maintenance, with stable signals. Suitable for various processes such as carbonitriding, nitriding, carbonitriding, super carbonitriding, and nitrogen-based atmosphere carbonitriding.
