Gas Permeation Analyzer AUTO N53/1 Product introduction This product is based on the test principle of the differential pressure method and is designed and manufactured with reference to GB/T 1038, ISO 2556 and other standards. The unique drawer-type diaphragm test chamber makes the operation more convenient. It is suitable for the gas permeability test of films, sheets, paper, packaging and related materials in the fields of food, medicine, medical equipment, daily chemicals, photovoltaic electronics, etc. It provides a wide range of high, medium and low gas barrier materials. , High-efficiency gas transmission rate detection. Test principle AUTO N53/1 gas permeability tester adopts the principle of differential pressure method. Place the processed sample between the upper and lower chambers, use a vacuum pump to evacuate the entire gas circuit system, and then add an atmospheric pressure experimental gas to the upper chamber to form a constant pressure difference between the upper and lower chambers. Under the action of the pressure gradient, the gas permeates from the upper cavity to the lower cavity through the film, and the system can calculate the barrier performance parameters such as the gas permeability of the sample through the pressure change of the lower cavity.
