Gas Permeability Analyzer


Compare

Gas Permeability Analyzer can tests the O2, CO2, N2 etc. gas transmission rate of plastic film, composite film, aluminum foil, thin sheets, rubber, porcelain, solar panel, medical patch and so on.

 

Working Principle

Differential-pressure method. Test sample separates test chamber into upper room and lower room, between which keeps a constant pressure difference (100KPa). Gas molecules penetrate through sample from higher pressure room into lower pressure room; measure the pressure change in lower pressure room and calculate gas transmission rate.

Standards

GB/T 1038, ISO 2556, ISO 15105-1, ASTM D1434

 

Features

  • Three test chambers, each with independent sensor and test data; can test three samples (but one test gas) at the same time; each chamber can stop and change sample independently.
  • Professional sensor, high precision.
  • Automatic test, auto judgment, auto stop.
  • Automatically keep pressure difference between upper and lower chambers.
  • Advanced electromagnetic temperature control technology, program controlled, auto increase and decrease; integrated design; precision 0.01℃.
  • High precision, can test aluminum foil.
  • Three test modes: high barrier, low barrier and medium barrier test.
  • Can expand test range to 600000 cm3/m224h·0.1MPa.
  • Can run long time without maintenance; over pressure auto protection.
  • LCD display test data.
  • Profesional software, simple interface, easy to use; flexible setting of test process.
  • Real time display curves of transmission rate, pressure, differential pressure, temperature.
  • Can zoom and move curves freely, so as to make detail analysis.
  • Professional test report, can export file in Office, PDF format etc.
  • Calibrated by Standard Film or by pressure.
