N600 Battery Diaphragm Air Per
meability Tester
Application
To test the air permeability of the battery diaphragm.
Operating principle
Gurley Method：To measure the time taken to pass 100 ml of gas at a constant pressure difference of 1.23 kpa.
Schopper-Riegler Method： Select the appropriate test duration and determine the air flow rate through the sample by measuring the volume under the constant pressure difference of 1.00 kPa±0.01kPa or 2.50±0.01kPa
Bendtsen method：At a constant pressure difference of 1.47kPa, the air flow through the test surface was recorded after clamping for 5s.

The three test methods: Gurley method, Schopper Method, and Bentley method are integrated into one machine for users to choose freely to meet the test needs of different users.
The pressure difference of the instrument is adjustable in the range of 0-3KPa, and the accuracy is 0.01kPa, which fully meets the test pressure requirements of the three methods.
The instrument has a large test volume of 1L, which fully meets the volume requirements of the three methods.
Free conversion between test area 10.0cm2 and 6.42cm2 by adding a mask.
The instrument comes with a temperature and humidity sensor to monitor the temperature and humidity of the test chamber in real time.
The instrument has good sealing performance and the air leakage volume does not exceed 1.0ml / h.
The instrument comes with a display screen and PC software, which can be operated offline and connected to a computer for simultaneous testing.
