PERME^TM  OX2/231 Oxygen Permeability Tester is applicable for the oxygen transmission rate determination of plastic films, laminated films, sheets as well as packages, like plastic bottles and pouches.
Characteristics
Mini-computer control; LCD displays data, results and curves;
Manu interface, PVC operation panel;
Aerage value of 3 chambers only;
Constant temperature control (optional purchase);
Constant humidity control (optional purchase);
Two testing modes of film and package (optional purchase);
Automotive power failure recovery;
Rapid calibration with reference film;
Mini-printer;
RS232 interface;
Network transmission interface for LAN data management and Internet data transmission.
Principle
Oxygen flows in one side of the film, and nitrogen flows on the other side. The oxygen molecules permeate through the film and into the nitrogen side, and are then carried to the sensor by the flowing nitrogen. By analyzing the oxygen concentration measured by the sensor, oxygen transmission rate and other parameters can be calculated. As to packages, nitrogen flows inside the packages, and oxygen flows outside the packages.
