The SFO2-100% oxygen sensor is an electrochemical partial pressure oxygen sensor for full scale oxygen concentration detection. It features a Molex 3-pin connector interface and a molded body design, offering fast response and long service life. Oxygen is reduced on the working electrode and the corresponding oxidation reaction happens on the anode. The redox current is proportional to the oxygen concentration.
