Laboratory Winch Dyeing Machine
GBN701 Face Mask Air Flow Resistance and Differential Pressure Tester
Application
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.
Standards
YY0469-2011, YY0969-2013
Principle
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.
