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.

High Accuracy
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.
