Principle High pure oxygen flows on one side of the film, high pure nitrogen flows on the other side of the film. Oxygen molecule passes the film into the nitrogen of another side, and is taken to the sensor by the flowing nitrogen. Test the transmission of oxygen by analyzing the concentration of oxygen detected by sensor. As for packaging container, nitrogen flows in the container, air or high pure oxygen covers the outside of the container. 3.
