Principle

Mount the pre-conditioned specimen between the upper and lower testing chambers. Oxygen or air flows in one side of specimen, high pure nitrogen flows in another side of the specimen. Oxygen molecules permeate through the specimen and enter into the high pure nitrogen side, which is then carried to the sensor by the flowing nitrogen. Obtain the oxygen transmission rate by analyzing the oxygen condensation detected by the sensor. For package test, high pure nitrogen flows in the package; air or pure oxygen flows around the outer side of the package.
