The S4OXV oxygen gas detection sensor is a battery-type sensor. It uses the reduction reaction of oxygen on the working electrode and the corresponding oxidation reaction of the anode material to generate current. The magnitude of the current is proportional to the concentration of oxygen. The oxygen can be determined by testing the magnitude of the current. the size of the concentration.
