Oxygen Transmission Rate Tester

The oxygen permeation testers OTR-O, -O3 and the models C230 are equipped with a coulometric sensor and measures the oxygen barrier of the material sample according to the equal pressure principle. Plastic films, laminated, extruded, coated or high barrier materials can be tested as well as packaging and containers made of plastic, rubber, paper or glass. The measurement can be carried out simultaneously in up to three independent chambers.

Not to forget the gas permeation devices GTR-G, which can measure all O2 ideally and easily as long as no high barrier materials are to be tested.
