Latest technology Gas Permeability Unit Manufacturing in China is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate as well as solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting and aluminum foils.

Latest technology Gas Permeability Unit Manufacturing in China conforms to the following standards:
ISO 15105-1, ISO 2556, GB/T 1038-2000, ASTM D1434, JIS K7126-1, YBB 00082003

Application:

Latest technology Gas Permeability Unit Manufacturing in China is applicable to the determination of gas permeability of:

1.Films
2.Sheeting
3.Various Gases
4.Inflammable, Explosive Gases

Features:

  • Gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of the specimen could be obtained at one operation
  • 3 distinct or equivalent specimens could be tested individually with independent test results at one operation
  • Wide range and high precision temperature and humidity control to meet various test conditions
  • The instrument comes with two test modes: proportional mode andstandard mode
  • Test range could be extended based on user requirements to test the materials with high permeability
  • Test results could be easily obtained even at extreme condition by data fitting function, which could work at any temperature
