Operating Principle：
Based on the Coulometric Sensor Method. The pre-conditioned specimen is fixed in the middle of the test chamber. High-purity oxygen flows in the upper chamber of the film, and high-purity nitrogen (carrier gas) flows in the lower chamber. Oxygen molecules permeate through the film and diffuse into the nitrogen on the other side, being carried to the sensor by the flowing nitrogen. By analyzing the oxygen concentration measured by the sensor, the oxygen transmission rate (OTR) is calculated.
