Working principle
It adopts Coulometry theory, use the high precision sensor to test the oxygen transmission rate (OTR) of flexible packaging materials.
The testing chambers including upper and nether parts, the sample film is fixed between the two chambers, the high pure oxygen (O2) circulate in the upper chamber of the film, and the high pure nitrogen (N2) circulate in the nether chamber of film, the oxy
