UL817 Protective Mask Carbon Dioxide Volume Test Machine
Respiratory Protective Mask Carbon Dioxide (CO2) Volume Test Machine
Description:
The mask dead space detection device is used to detect the dead space of the protective mask, that is, the volume fraction of CO2 in the inhaled gas.
Comply with the standards:
TAJ1001—2015
GB2890-2009
Structure principle:
The main components of the test device include: test head mold, mechanical artificial lung with solenoid valve, connecting pipe, flowmeter, CO2 gas analyzer and control system.
The test device is driven by the low-speed motor of the detection device through the control system to drive the artificial lung to make reciprocating motion to simulate the actual breathing process of human beings. Pushing is equivalent to inhaling, and returning is equivalent to exhaling. In terms of this process, the upper part of the cupboard is completed. At the same time, a certain amount of high concentration CO2 was injected into the breath, and the whole process of respiration was detected by CO2 gas analyzer.
