  • 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
