Oxygen permeability testerIt is a specialized equipment used to measure the oxygen permeability of materials, widely used in quality control in industries such as packaging, food, and medicine. Its working principle is to evaluate the barrier performance of the 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 permeability testerIt 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.

Oxygen permeability testerThe core technical parameters include measurement range, accuracy, temperature and humidity control capability, etc. The measurement range usually ranges from a fewcc/m²·dayUp to several thousandcc/m²·dayUnequal, the accuracy can reach ±1%The ability to control temperature and humidity is crucial for ensuring the accuracy of test results, and the general temperature control range is15-50℃, humidity control range is10-90%RH.

in the selectionOxygen permeability testerWhen doing so, it is necessary to consider factors such as the type of sample, testing standards, and laboratory environment. Common testing standards includeASTM D3985TheISO 15105-1andGB/T 19789Wait. In addition, the ease of operation, maintenance costs, and after-sales service of the equipment are also important considerations.
