QT-OPT-210 Oxygen Permeability Tester is designed to test the oxygen transmission rate (OTR) of a wide range of packaging materials such as plastic film, composite film, coextrusion film, aluminum foil, aluminum-plated film, infusion bag, sheets, solar panel, cellophane, ceramics, porcelain, and various containers like bag, pouch, bottle, can, bowl, box that widely used in the industries of food, pharmaceuticals, personal care, household, electronics by coulometric sensor method.

ASTM D3985 Standard Test Method for Oxygen Gas Transmission Rate through Plastic Film and Sheeting Using a Coulometric Sensor. This test method covers a procedure for determination of the steady-state rate of transmission of oxygen gas through plastics in the form of film, sheeting, laminates, coextrusions, or plastic-coated papers or fabrics. It provides for the determination of (1) oxygen gas transmission rate (OTR), (2) the permeance of the film to oxygen gas (PO2), and (3) oxygen permeability coefficient (PO2) in the case of homogeneous materials.

  • Professional test report can be exported as Office Word or PDF.
  • Can expend to 12 chambers maximum.

Working Principle

Coulometric sensor method. Test sample is fixed in the middle of test chamber to separate the chamber into upper room and lower room. When oxygen and nitrogen flow in upper and lower room respectively, the oxygen molecules penetrate through the sample into the lower room, and coulometry sensor system detect and analyze the oxygen contented and calculate the oxygen transmission rate. When testing the container, oxygen will be released outside and nitrogen inside of the container.
