Face Mask Air Flow Résistance And Differential Pressure Tester -GBN701 used for face mask air flow résistance and differential pressure testing to check breathability and can also be used to check differential pressure of textile materials gas exchanger. used for face mask air flow résistance and différentiel pressure testing to check breathability and can also be used to check differential pressure of textile materials gas exchanger. Application Used for face mask air flow résistance and differential pressure testing to check breathability and can also be used to check differential pressure of textile materials gas exchanger. Principle 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 différence is calculated. Standards YY0469-2011, YY0969-2013 Features I Equipped with spécial sample grip, easy to use. I Built-in HD touch screea I Built-in micro printer, easy to print test results. I Equipped with high-precision differential pressure sensor, digitally display the pressure différence between the two sides of the sample; I Equipped with high-precision gas flow control, real-time digital display of air flow to stably control air flow, manually setting available. I Test time can be adjusted according to test requirements
