The KQT-O2 oxygen gas detection sensor is a battery-type sensor. It generates an electric current through the reduction reaction of oxygen on the working electrode and the corresponding oxidation reaction of the anode material. The magnitude of the current is proportional to the concentration of oxygen. The concentration of oxygen can be determined by measuring the magnitude of the current.
