  • 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.

Test StandardNote1

ISO 5636, SJT 1071.9, GB/T 36363-2018

ApplicationsNote1

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