Gas exchange pressure difference tester
1. Main Application: The gas exchange pressure difference tester is suitable for measuring the gas exchange pressure difference of medical surgical melt-blown filter materials, and can also be used to measure the gas exchange pressure difference of other textile materials.
2. Instrument features:
1. It uses suction gas source as the power source of the instrument, which is not limited by the space of the test site; 2. It is equipped with a high-precision differential pressure sensor, which digitally displays the pressure difference on both sides of the sample; 3. The special sample clamp ensures that the sample is firmly clamped.
3. Technical indicators:
1. Air source: suction type; 2. Air flow: 8L/min; 3. Sealing method: end face sealing; 4. Sample air permeability: Ф25mm; 5. Pressure difference sensor range: 0~500pa; 6. Display method: digital display of pressure difference; 7. Power supply: 220V, 50Hz.
IV. Applicable standards:
YY0469-2011 "Medical surgical meltblown filter material"
YY0969-2013 "Disposable medical meltblown filter material"
EN14683:2014
