The S4LFO2-25 lead-free oxygen gas detection sensor is a lead-free, long-life sensor. It utilizes the reduction reaction of oxygen on the working electrode and the oxidation reaction on the counter electrode to generate current. The magnitude of the current is directly proportional to the oxygen concentration. The oxygen concentration can be determined by measuring the magnitude of the current.
