Gas permeation tester (N530),GTR

Gas permeation tester,model N530 Function and usage N530 has permeation tester test the gas permeability of various films, infusion bags and all kinds of packaging materials for O2, CO2, N2 and other gases through the barrier properties.It is designed and manufactured according to the standards of ISO 2556-2001, ISO15105-1, GB / T 1038-2000, ASTM D1434-82 (2003), YBB00082003. Test principlesN 530 Gas Permeation Analyzer designed using the principle of differential pressure method, prepration samples will be placed between in the test chamber with high / low pressure , and clamping it ,then make the whole test system to have a vacuum processed, input test gas the high-pressure test chamber to ensure on both sides of the test samples have a constant pressure, the gas under the role of pressure pass through film from high-pressure chamber to the low pressure chamber to infiltrate, observe the changes pressure in low-pressure chamber to caculate barrier parameters of the sample.
