Test principle
SN-Y02 oxygen permeability tester adopts the principle of coulometric method. The pre-treated sample is fixed in the middle of the test cavity, high-purity oxygen flows in the upper cavity of the film, and high-purity nitrogen (carrier gas) flows in the lower cavity. Oxygen molecules diffuse through the film into the nitrogen on the other side and are carried to the sensor by the flowing nitrogen. The oxygen concentration measured by the sensor is analyzed to calculate the oxygen permeability.
