ASTM D3985, ASTM F1307, ASTM F1927,GB/T 19789,GB/T 31354,DIN 53380-3,JIS K7126-2-B,YBB 00082003-2015
The oxygen transmissivity tester is designed and manufactured according to ASTM D3985 standard using coulomb oxygen sensor and ISOBARIC test principle. It is applicable to high and medium oxygen and air barrier materials to test their oxygen transmissivity.
High precision coulomb oxygen sensor improves the accuracy and stability of the test
• 7-inch high-definition LCD touch screen, more intuitive content and easier operation
• Independent single chamber test, one sample can be tested at a time
• Wide range, high precision, automatic temperature control to meet the test under various test conditions
• Test results support multi format storage and data output, including experimental report Excel and cloud sharing
• The product complies with the GMP user's multi-level permissions
• Single and group statistical analysis of test results can be conducted
• It has ISP online control and upgrade functions, and can change the test function remotely as required
• Special computer communication software, which can perform real-time display of test, data analysis and processing, and data storage
The processed sample is clamped on the test chamber. Oxygen or air flows on one side of the film, and high-purity nitrogen flows on the other side of the film. Oxygen molecules diffuse through the film to high-purity nitrogen on the other side, which is carried to the sensor by flowing nitrogen. After the oxygen concentration measured by the sensor is analyzed, oxygen transmission test data is issued after reaching osmotic balance.
