The MH3205 portable infrared CO/CO2 analyzer employs non-dispersive infrared (NDIR) technology to measure the concentrations of CO and CO2 in ambient air. It is suitable for CO and CO2 concentration measurement in routine ambient air quality monitoring, as well as in public places, workplaces, occupational protection, civil air defense systems, health and epidemic prevention, tunnels, and comparison of measurement results with online monitoring instruments.
