AUTO N56/1 Gas Permeability Analyzer - Differential Pressure Method Product introduction This product is based on the test principle of differential pressure method, and is designed and manufactured with reference to GB/T 1038, ISO 2556 and other standards. Adopt high-precision pressure sensor and automatic pressure difference technology, high test accuracy. It is suitable for the gas permeability test of films, sheets, papers and related materials in the fields of food, medicine, medical equipment, daily chemistry, photovoltaic electronics, etc., and provides a wide range and high efficiency gas transmission rate detection for high, medium and low gas barrier materials. Test Principle AUTO N56/1 Gas Permeability Analyzer 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 experimental gas of large gas pressure 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 chamber to the lower chamber through the sample, and the system can calculate the barrier performance parameters of the sample through the pressure change of the lower chamber. Standard GB/T 1038, ISO 2556, ISO 15105-1, ASTM D1434, JIS K7126-1, YBB 00082003
