Testing Principle
Y110L oxygen transmission rate tester adopts the principle of coulombic electricity method. The pre-treated specimen is fixed in the middle of the test chamber, high purity oxygen flows in the upper chamber of the film, high purity nitrogen (carrier gas) flows in the lower chamber, oxygen molecules diffuse through the film to the nitrogen gas on the other side and are carried to the sensor by the flowing nitrogen gas, and the oxygen transmission rate is calculated by analyzing the oxygen concentration measured by the sensor.
