Applications

Medical Mask Differential Pressure Tester or Medical Mask Differential Pressure Tester, is a lab testing instrument for determination breathability of medica face masks, the test principle is,  through measuring the differential pressure required to draw air through a measured surface area at a constant air flow rate, to test the air exchange pressure of the medical face mask material, which indicates the breathability of medical face masks.

Built-in water-filled differential manometer is used to measure the differential pressure, a mass flow meter is used for measurement of the airflow. An electric vacuum pump draws air through the medical mask breathability tester and a needle valve is used to adjust the airflow rate.

Medical face masks differential tester complies with standards like EN 149. EN 14683. ASTM F2100. MIL-M-36954C, GB 19083. GB 2626. YY/T 0969-2013.
