Differential Pressure Method Gas Transmission Tester N500 2.0 Introduction This product is designed and manufactured based on the differential pressure test principle and in accordance with ISO 2556 and other standards. It uses high-precision pressure sensors and automatic differential pressure maintenance technology to achieve high test accuracy. It is suitable for testing the gas permeability of films, sheets, papers, packaging and related materials in the fields of food, medicine, medical equipment, daily chemicals, photovoltaic electronics, etc., and provides a wide range of high-efficiency gas permeability testing for high, medium and low gas barrier materials. Test Principle The N500 2.0 gas permeability tester uses the principle of differential pressure method. The processed sample is placed between the upper and lower chambers, and the entire gas path system is evacuated using a vacuum pump. Then, an atmospheric pressure of experimental gas is added to the upper chamber to form a constant pressure difference between the upper and lower chambers. Add.: No. 3, Linjiang Road, Huangpu District, Guangzhou, Guangdong Province, China

Under the action of the pressure gradient, the gas penetrates from the upper chamber to the lower chamber through the film, and the system can calculate the gas permeability and other barrier performance parameters of the sample through the pressure change in the lower chamber.
