Medical Mask Differential Pressure Tester
Face Mask Air Exchange Pressure Difference Tester 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.
