45L/Min CO2 Concentration Dead Space Mask Test Machine EN149

Respirator Dead Space Test Machine EN149 CO2 content in inhalation air

MODEL: SM-4312

The Dead Space Test Machine of respirator is used to detect the volume fraction of carbon dioxide inhaled in the last breath of particle respirator.

Wear the respirator on the matching test head mold in an airtight manner, open the dead space test machine, continuously monitoring and recording the concentration of CO₂ in the inhaled air and the environment until it reaches a stable value.

SM-4312 Dead Space Tester is composed of respiratory simulator, test head mold, CO₂ concentration meter, air pump, flowmeter, air speed meter and microcomputer control system.
