Marathon is an American-made imported sensor. Its two brands address the issue of diameter singularity, offering a wider range of options. Marathon features a unique electrode structure, ensuring probe stability and durability. The protective tube is made of RA330 alloy, a material known for its red hardness and corrosion resistance, maintaining stable performance at high temperatures. The working principle primarily utilizes the electrical conductivity of zirconia to measure oxygen concentration in gases. Marathon models typically start with F or MMI, featuring a complete range, high-temperature resistance, but are fragile. Available lengths include 600, 800, 1000, 1200, and 2000mm, with diameter options of 25mm and 22mm. Model examples: F10040-600N, F10043-600K, F10045-800N, F10048-800S, F1048-800K, F10050-1000N, F10053-1000K, F10057-1200N.
