Face Mask Air Flow Resistance and Differential Pressure Tester

The face mask air flow resistance and differential pressure tester is used to check breathability and can also be used to check differential pressure of textile materials gas exchanger.  The output of the air flow is set by a gas flow meter, the air flow passes through a certain area of the test sample, the current pressure is detected by a pressure sensor, and the pressure difference is calculated. The application covers testing and requirements for materials used in the construction of medical face masks that are used in providing healthcare services such as surgery and patient care.
