    Mask gas exchange pressure difference measuring instrument


    Overview


    The mask gas exchange pressure difference tester (gas exchange pressure difference tester) is based on the test principle of the standard YY0469-2011 "Technical Requirements for Medical Surgical Masks", which uses a differential pressure sensor to achieve the pressure difference detection between the internal pressure and the external pressure of the placed mask. It is equipped with special tooling devices to achieve the test sealing performance of the product. It is mainly used for measuring the gas exchange pressure difference of medical surgical masks / mask fabrics, and can also be used to measure the gas exchange pressure difference of other textile materials.
