Used for face mask airflow resistance and differential pressure testing to check breathability and can also be used to check differential pressure of textile materials gas exchanger.
YY0469-2011, YY0969-2013
The output of the airflow is set by a gas flow meter, the airflow passes through a certain area of the test sample, the current pressure is detected by a pressure sensor, and the pressure difference is calculated.
