|Purpose:||Determination Of Dead Cavity Performance Of Masks||Test Standard:||ISO 22609, ASTM F1862-07|
|Power:||AC 220V± 10% 50Hz||Dimension:||910mmx420mmx400mm(L*W*H)|
Surgical Mask And Protective Clothing Synthetic Blood Penetration Resistance Testing Equipment
Mask Dead Cavity Detector is mainly used to detect the dead cavity of respirator, that is, the volume fraction of CO2 in inhaled air.
The testing principle of the equipment is to detect, record and calculate the change of the carbon dioxide concentration of the inhaled gas during the whole test process.
|Breathing simulator simulates breathing frequency modulation||10~40 times/min|
|Simulated tidal volume regulation range||0.5~3.0L/min|
|Volume fraction of carbon dioxide source||5.0±0.1%|
|Carbon dioxide flowmeter range||≤ 40L/min|
|Carbon dioxide analyzer range||≤ 12%, accuracy ≤0.1%|
|Ventilating fan||Wind speed 0.5 m/s|
|Breathing rate||20 times/min|
