ZY-8808 Mask gas exchange pressure difference tester
I. Scope of application:
It 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.
2. Standards:
YY0469-2011 "masks", YY0969-2013 "disposable masks".
Specifications:
* Air source: suction;
* Air flow: 8L / min;
* Sealing method: O-ring seal;
* Sample ventilation aperture: Ф25mm;
* Differential pressure sensor range: 0 ～ 500pa;
* Display mode: Digital display pressure difference;
* Power: 220V, 50Hz.
Fourth, the characteristics of the instrument:
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.
