Oxygen Permeability Analyzer(OTR tester)
Application
To test the oxygen transmission rate (OTR) of packaging materials, such as plastic film, composite film, coextrusion film, aluminum foil, aluminum-plated film, infusion bag, sheets, 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.
Working Principle
Coulometric sensor method. Fix the test sample in the middle of test chamber to separate the chamber into upper room and lower room. When oxygen flows in upper room and nitrogen in lower room, the oxygen molecules penetrate through the sample into the lower room, and coulometry sensor system detect and analyze the oxygen content and calculate the oxygen transmission rate. To test container, oxygen is outside and nitrogen is inside of the container.
