China Plastic Oxygen Permeability Tester


ASTM D3985 Oxygen Gas Transmission Rate Tester is based on the coulometric sensor method and available for the OTR test of flexible films, sheeting and packages. It can test 3 specimens in one operation with independent results.


Plastic films, aluminum foil, aluminized films, plastic composite films, paper-plastic composite films, coextruded films, aluminum foil composite films and many others.


Plastic, rubber, paper, paper-plastic composite, glass and metal packages, e.g. red wine bottles, blister, various plastic bottles, Coke bottles, peanut oil packages, Pak materials, vacuum bags, metal three-piece cans, plastic packages for cosmetic, soft tubes for toothpaste, jelly and yogurt cups.

3 Chambers temperature sensor embedded in

Environment temperature and humidity sensor inside

Chambers water bath technology

Unit based on embedded system,24bit Δ-Σ AD

Pressure, oxygen and temperature overload protection

Traceable reference film calibration

Supports DSM system (DSM, lab data management system)



The specimen is clamped between the upper and lower chamber, the upper chamber is purged by a oxygen stream, and the other side of specimen, lower chamber is purged by a stream of nitrogen, due to the effect of oxygen concentration gradient at two sides of the specimen, oxygen molecules will permeate through the specimen into the nitrogen side, penetrated oxygen molecules will be carried to the coulometric sensor which generates the proportional signal, so oxygen transmission rate and permeability coefficient will be obtained by calculating the sensor signal.


The package is mounted on the lower chamber, the outside of the package is air or a pure oxygen stream, the inside of the package is purged by a nitrogen stream, oxygen will permeate through the wall into the inside of the package, penetrated oxygen molecules will be carried to the coulometric sensor which generates the proportional signal, so oxygen transmission rate will be obtained by calculating the sensor signal.
