OTR-1901 Oxygen Permeability Tester

Application

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.

Films:

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

Packages:

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

Principles

Film:

The specimen is clamped between the upper and lower chambers. The upper chamber is purged with an oxygen stream while the lower chamber is purged with a nitrogen stream. Due to the oxygen concentration gradient, oxygen molecules permeate through the specimen and are carried to a coulometric sensor, which generates a proportional signal from which the oxygen transmission rate and permeability coefficient are calculated.

Package:

The package is mounted on the lower chamber with the outside exposed to air or a pure oxygen stream and the inside purged by a nitrogen stream. Oxygen permeates through the package wall, and the penetrated molecules are carried to the coulometric sensor to determine the oxygen transmission rate.
