Full Description

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.

ApplicationsNote1

Basic Applications

Test the gas permeability of battery diaphragms, breathable films and other relative polymer products.
