BTY-B2P 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 Features
- 3 equivalent specimens can be tested simultaneously with the average value as test result
- The system supports unit conversion function to meet user’s requirements for special test
- The instrument is controlled by computer with automatic test process
- Two test modes of proportional and standard modes are available
- Customization of test functions is available for special test materials
- Equipped with RS232 port for convenient data transfer
- Supports LystemTM Lab Data Sharing System for uniform and systematic management of test results and test reports
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.
Standards
This test instrument conforms to the following standards: ISO 5636, SJT 1071.9
Applications
This instrument is applicable to the determination of gas permeability of:
