Gas Permeability Test for battery diaphragms

Product catalog summary

Overview
The BTY-B2P Gas Permeability Tester by Labthink Instruments Co., Ltd. is designed to measure the gas permeability of battery diaphragms, breathable films, and similar polymer products using the differential pressure method.

Professional Technology

Simultaneous testing of 3 specimens with average value as the result.
Unit conversion function for special test requirements.
Computer-controlled with automatic test process.
Two test modes: proportional and standard.
Customizable test functions for special materials.
RS232 port for data transfer and support for Lystem Lab Data Sharing System.

Test Principle
The instrument operates under specific temperature and humidity conditions, creating a constant gas differential pressure across the specimen. Gas transmission rate and other parameters are calculated from pressure changes.

Standards
Conforms to ISO 5636 and SJT 1071.9 standards.

Applications
Primarily used for testing gas permeability of battery diaphragms and breathable films.

Gas Permeability Test for battery diaphragms-1

PERME® BTY-B2P Gas Permeability Tester LOMlHIlK BTY-B2P 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. Professional Technology • 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 a computer and test process is finished automatically • Two test modes of proportional and standard modes • Customization of test functions is available for special test materials • Equipped with RS232 port for convenient data transfer • Support Lystem™ Lab Data Sharing System for uniform and systematic management of test results and test 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. This test instrument conforms to the following standards: This instrument is applicable to the determination of gas permeability of: Test the gas permeability of battery diaphragms, breathable films and other relative polymer Basic Applications Technical Specifications Specifications Film Test Pressure Range 0~20 KPa (customization available for others) Test Area 0.025 sq.in.
