Testing Principle
The sample is clamped between the test chambers, oxygen or air flows on one side of the film, and high-purity nitrogen flows on the other side of the film. Oxygen molecules diffuse through the film into the high-purity nitrogen in the other side. The flowing nitrogen is carried to the sensor. Through the analysis of the oxygen concentration measured by the sensor, the oxygen transmittance is calculated.
