Permeation R and permeability coefficient P are not to change with the variation of pressure difference.
Three test chambers are tightly designed together, which facilitates temperature and humidity control. The comparison of test results of the three test chambers will be more rational and precise as the humidity and the temperature are evenly distributed due to the patented technique, especially when the test materials are temperature and humidity sensitive. External humidity generator is optional for humidity controlling.
