Medical Face Mask Air Exchange Pressure Difference Tester
Medical Face Mask Air Exchange Pressure Difference Tester G289 meets 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.
Features:
1. Adopt suction air source as the power source of the instrument, not limited by the space of the test site;
2. Equipped with a precision differential pressure sensor, which digitally displays the pressure difference on both sides of the sample;
3. The special sample holder ensures that the sample is firmly held.
Medical Face Mask Air Exchange Pressure Difference Tester G289 Test Standards:
YY 0469-2011:Surgical mask
YY 0969-2013:Single-use medical face mask
EN 14683:2014:Medical face masks - Requirements and test methods
Medical Face Mask Air Exchange Pressure Difference Tester G289 is suitable for the measurement of gas exchange pressure difference of masks, and can also be used to determine the gas exchange pressure difference of other textile materials.
