Mass testing oxygen permeability testerThe working principle is to evaluate the barrier performance of a material by placing the sample in a specific environment and measuring the amount of oxygen permeation per unit time. According to different application requirements, oxygen permeation meters can be divided into two types: differential pressure method and isobaric method. The differential pressure method is suitable for high barrier materials, while the isobaric method is suitable for low barrier materials.
