The Medical Face Mask Differential Pressure Tester is designed to evaluate the breathability and airflow resistance of medical and surgical face masks by measuring the pressure difference across the mask under a controlled airflow. It is suitable for quality control, product development, and performance testing of medical face masks and related protective materials. The tester can be used with applicable standards such as EN 14683 and ASTM F2100.

Application

It is used for the determination of gas exchange pressure difference of medical surgical masks and can also be used to determine the gas exchange pressure difference of other textile materials.
