Working Principle of TT-N530G Gas Permeability Analyzer
According to the principle of differential pressure method. Place the processed sample between the upper and lower chambers, use a vacuum pump to evacuate the entire gas circuit system, and then add an
experimental gas of an atmospheric pressure to the upper chamber to form a constant pressure difference between the upper and lower chambers. Under the pressure gradient, the gas permeates
from the upper chamber to the lower chamber through the membrane, then the system can calculate the barrier performance parameters such as the gas permeability of the sample through the pressure change of the lower chamber.
