This air permeability tester Gurley method to test the air permeability of battery diaphragm, air permeability membrane and related polymer materials, as well as cigarette paper and various papers.
Features
• Fully automatic measurement of the gas volume passing through the sample, leaving the traditional manual sliding cylinder gas volume measurement method
Full automatic high-precision pressure control technology, with pressure accuracy better than 0.01kPa
• Test pressure can be set freely through software
• Three independent test chambers, which can complete three sample tests in a single test
Pneumatic sample clamping saves time and effort, with consistent clamping force and better sealing
• Core sensors and pneumatic control systems are all from world-renowned manufacturers, with low failure rate and long service life
With the function of automatic detection of temperature and humidity in the test environment, it can automatically record the test conditions
• The system adopts electronic intelligent control, and the whole test process is completed automatically
• The product complies with GMP multi-level authority
• Micro printer, note printing test statistical results at any time
• Support s/100 mL, um/(Pa · s) multi unit display, applicable to different standard testing requirements
• The software has multi-level permission management, audit tracking and other functions (optional)
Test method
Under the pressure of 1.21kPa in the laboratory environment, record the time required for 100mL of test gas to pass through the battery diaphragm of a specific area.
