PERME OX2/231 Oxygen Transmission Rate Instrument is applicable for the oxygen transmission rate determination of plastic films, laminated films, sheets as well as packages, like plastic bottles and pouches.

Oxygen Transmission Rate Instrument conforms to ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, ISO 15105-2, JIS K7126-B, YBB 00082003 and GB/T 19789.

Oxygen Transmission Rate Instrument 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.
