Applications:
Medical Mask Differential Pressure Tester or medical face mask breathability 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.
Product Information:
The Medical Mask Differential Pressure Tester is a professional testing instrument designed to measure the pressure difference across medical masks, protective masks, and other filtration materials. By simulating the human breathing process, the tester allows a specified airflow to pass through the mask sample and measures the differential pressure on both sides of the sample, evaluating the air permeability and breathing comfort performance of the mask material.
Standards:
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.
