Product Description
Gas Permeability Tester

We are devoted to manufacture, supply and export an assortment of premium grade Gas Permeability Tester. Provided tester is taken into use for the measuring of gas transmission rate, permeability and solubility coefficient of several sheets, films and foils. It is factory-made by our adroit technocrats employing superior quality machinery and separated pressure technique in line with global standards of quality. To cater to the diverse demands of customers across the world, we are providing this Gas Permeability Tester in numerous stipulations at nominal rate.

Features:
  • Application explicit design
  • Strong construction
  • Precise operation
  • Trouble-free installation
Professional Technology
  • Gas transmission rate, diffusion coefficient, solubility coefficient, and permeability coefficient of the specimen can be attained at single operation
  • 3 different or equivalent samplings could be tried separately with independent examination results at single operation
  • Wide range and high precision temperature and humidity control to meet various test conditions
  • The instrument is offered with two test methods: standard mode and proportional mode
  • Test choice could be stretched based on user necessities to test the constituents with high penetrability
  • The instrument could be used to test poisonous, inflammable, and explosive gases (customization required)
  • The instrument is measured by a computer and the examination procedure is automatic
  • Orientation film for fast setting to safeguard accurate and universal examination data
  • Typical RS232 port for suitable data transfer
  • Provision System Lab Data Sharing System for unchanging organization of test reports and test results

Test Principle

The pre-conditioned example is built in the gas diffusion cell as to make a sealed barricade between two compartments. The lower-pressure compartment is firstly expatriate, trailed by the evacuation of the whole cell. A movement of gas is afterward presented into the expatriated higher-pressure compartment and a continuous pressure alteration is produced between two compartments. The gas permeates via the sample from the higher-pressure lateral into the lower lateral. The gas permeability and additional blockade possessions of the sampling can be attained by examining the pressure fluctuations in the lower compartment.

This test instrument imitates to the subsequent standards: ISO 2556, ISO 15105-1, ASTM D1434, JIS K7126-1, GB/T 1038-2000, YBB 00082003
