Differential Pressure Tester
Medical face mask differential pressure tester also called mask breathility tester is to determine the breathability of medical face mask materials. The tester can measure the differential pressure (Delta P) required to draw air through a measured surface area at a constant air flow rate is used to measure the air exchange pressure of the medical face mask materials. By providing the suction air through the holding sample, the tester can measure the Delta P by differential pressure transducer. It is to determine the air permeability and using comfort of the materials for medical mask.

Mask Differential Pressure Tester TN141
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, tester complies with EN 14683, ASTM F2100, YY 0469 medical face masks testing standards.
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.
Medical face masks differential tester complies with standards like EN 14683, ASTM F2100, YY 0469.
