Oxygen Permeation

The test film is separated into two separate air flow systems, one for the flow of gas (oxygen or air), the other side is the flow of nitrogen. The pressure is equal on both sides of the specimen, so this method is also called "the isopiestic method". Because the concentration of oxygen is different, and the oxygen concentration is from high to low concentration. Illinois oxygen meter using our patented linear sensor, thus the oxygen penetration rate, the instrument of all programming and setting work is done with PC, and with automatic closing function, once the tested samples have flaws, exceeding the scope of the instrument, the instrument will automatically shut down to protect the sensor.
