BTY-B3P Gas Permeability Tester
It is based on the differential pressure method and is professionally applicable to the determination of the gas permeability of battery diaphragms, breathable films and other related polymeric products.
Under a certain temperature and humidity, a constant gas differential pressure is generated between the two sides of the sample. The gas transmission rate and other parameters can be obtained by analyzing and calculating the pressure changes on the lower pressure side.
