BTY-B3P Gas Permeability Tester is based on the differential pressure method, and is professionally applicable to the determination of gas permeability of battery diaphragms, breathable films and other relative polymer products.
Product FeaturesNote1
- The instrument is controlled by computer with automatic test process
- Touch screen, easy to learn and easy to operate
- Imported high precision pressure sensors are used, which guarantees the testing accuracy and repeatability
- Imported pneumatic control system with ultra-low failure rate and extremely long service life, which guarantees the seal performance of the whole system
- Environmental temperature and humidity are monitored and recorded in real time
- 3 equivalent specimens can be tested simultaneously with the average value as test result
- Pressure curves are displayed in real time for observation and analysis of the permeation process
- The system supports unit conversion function to meet user’s requirements for special test
- Customizations are available for special testing function, specimen size or test pressure
Test Principle
Under certain temperature and humidity, a constant gas differential pressure is generated between the two sides of specimen. The gas transmission rate and other parameters can be obtained by analyzing and calculating pressure changes in the lower pressure side.
