Gas Permeability Tester QT-GTR series, is the most advanced and competitive product line from Qualitest, to test the Gas Transmission Rate (GTR) of packaging materials by differential pressure method. Gas permeability is the ability of a barrier material to allow gases (O2, N2, CO2 etc.) to permeate through it in a specific time. Gas permeability may vary with temperature, humidity, pressure and specimen thickness.
