The AUTO Y36/1 Oxygen Permeability Analyser – Coulometric Sensor Method is crafted on the testing principle of the coulometric sensor method for measuring oxygen. It is meticulously designed and manufactured in accordance with standards such as GB/T 19789, ASTM D3985, and others. Employing a high-precision imported oxygen sensor for superior test accuracy, it is apt for assessing the oxygen transmission performance of films, sheets, paper, packaging, and related materials in diverse industries including food, medicine, medical equipment, daily chemicals, and photovoltaic electronics. This analyser offers a broad spectrum of high-efficiency oxygen transmission rate detection for materials with high, medium and low oxygen barrier properties.

Test Principle The AUTO Y36/1 Oxygen Permeability Analyser utilises the Coulometric sensor method. The pre-processed sample is secured in the center of the test chamber. High-purity oxygen flows in the upper chamber of the film, while high-purity nitrogen (carrier gas) flows in the lower chamber. Oxygen molecules diffuse through the film to the nitrogen on the other side, and the flowing nitrogen gas carries the oxygen to the sensor. The oxygen transmission rate is then calculated by analysing the oxygen concentration measured by the sensor.

Standards GB/T 19789, YBB 00082003, ASTM D3985, ASTM F2622, ASTM F1927, ASTM F1307, ISO 15105-2, DIN 53380-3, JIS K-7126-B
