Oxygen permeability tester: technical analysis of Coulomb coulometric principle

【 Oxygen Transmittance Tester: Technical Analysis of Coulombic Electrometry Principle 】

The oxygen permeability tester, also known as the oxygen permeability meter, is an OTR oxygen permeability device based on the Coulomb coulometric testing principle, providing high-precision and high-efficiency oxygen permeability testing for high and medium gas barrier materials. The Coulomb coulometric method, also known as the isobaric method, will be analyzed in detail in this video using the C-series oxygen permeable equipment developed and produced by Jinan Languang Company. During the experiment, the pre processed sample is clamped between the testing chambers, with oxygen or air flowing on one side of the membrane and high-purity nitrogen flowing on the other side. Oxygen molecules diffuse through the membrane into the high-purity nitrogen on the other side and are carried to the sensor by the flowing nitrogen. By analyzing the oxygen concentration measured by the sensor, the oxygen permeability and other results are calculated. For packaging, high-purity nitrogen flows inside the packaging, while air or oxygen surrounds the outside of the packaging. Jinan Languang supplies multiple models of Coulomb coulometric oxygen permeability testers, which can accurately and effectively provide technical support for material oxygen barrier testing and research. We are always ready to have more in-depth technical discussions with you.
