To test the gas (O2, N2, CO2 etc) transmission rate (GTR) of packaging materials, such as plastic film, composite film, coextrusion film, aluminum-plated film, aluminum foil, infusion bag, sheets, paper, paper board, solar battery panel, cellophane, ceramics and porcelain, and various containers such as bag, pouch, bottle, can, bowl, box, widely used in the industries of food, pharmaceuticals, personal care, household, electronics and so on.

Pressure differential method. Fix the test sample in the middle of test chamber to separate the chamber into upper room and lower room, between which there is a constant pressure difference. The gas molecules penetrate through the sample from higher pressure room into lower pressure room, then the system monitor the pressure change in lower pressure room and calculate the gas transmission rate.
