Products meet the standard requirements, which is YY0469-2004 "Medical surgical mask technical requirements" and YY 0969-2013 "Disposable medical masks", medical face mask air exchange pressure difference tester is measured by gas pressure difference on both sides of the mask (ie the damping from the mask exert to the airflow) to determine the breathability of the mask, and the instrument test results is accurate.
The device 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。
