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。

1, using the suction gas source as the instrument power source, free from test space constraint;
2, with a high precision differential pressure sensor, digital show the sample pressure of both sides;
3, special sample holder to ensure a good clamping sample.
