The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. One chamber contains oxygen or air and the other chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing and calculating the signals. For package samples, high purity nitrogen flows inside the package, and oxygen or air flows outside.

- Be used to measure oxygen transmission rate of film and package specimens.
- Three test modes and is applicable to various materials with high, medium and low oxygen permeability.
- High precision oxygen sensor.
- Based on the equal pressure method.
- Three diffusion cells integrated in one instrument for individual or multiple tests, which improves test efficiency by 3 times.
- Be easily connected with 9 satellite bases together to accomplish up to 30 tests at the same time.
- Wide range and high precision of temperature and humidity control, adding humidity to two sides of the specimen, to support various combinations of non-standard test conditions.
- World leading pressure compensation technology ensures accurate and repeatable test results.
