Oxygen Permeability Tester OTR-1901

OTR-1901 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
Plastic, rubber, paper, paper-plastic composite, glass and metal packages, e.g.
red wine bottles, blister, various plastic bottles, Coke bottles, peanut oil
packages, Tetra Pak materials,vacuum bags, metal three-piece cans

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.
