Coulometric Sensor Method Oxygen Permeability Analyzer Y310L Introduction This product is designed and manufactured based on the coulometric oxygen sensor testing principle and in accordance with standards such as GB/T 19789 and ASTM D3985. It utilizes a high-precision imported oxygen sensor to ensure accurate test results. It is suitable for testing the oxygen transmission properties of films, sheets, paper, packaging, and related materials across industries such as food, pharmaceuticals, medical devices, daily chemicals, and photovoltaic electronics, providing efficient, wide-range oxygen transmission rate testing for materials with high, medium, and low oxygen barrier properties. Test principle The Y310L Oxygen Transmission Rate Tester operates based on the coulometric principle. A prepared specimen is secured between the two halves of the test chamber; high-purity oxygen flows through the upper chamber, while high-purity nitrogen (carrier gas) flows through the lower Add.: No. 3, Linjiang Road, Huangpu District, Guangzhou, Guangdong Province, China

chamber. Oxygen molecules permeate the film into the nitrogen stream and are carried to the sensor. The oxygen transmission rate is then calculated by analyzing the oxygen concentration measured by the sensor.
