Face Mask Differential Pressure Tester
This face mask differential pressure tester is used for testing the face mask’s differential pressure, then to check face masks’ breathability, it also can be used to check the differential pressure of gas exchanger for other textile materials.
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.
