AirGuardian CO2 monitor

 Carbon dioxide (CO2) is a gaseous component of the earth's atmosphere.

The concentration of CO2 in natural ambient air is about 0.04% or 400ppm. With each breath, humans convert oxygen (O2) into carbon диоксиде which is invisible and odorless, an increased CO2-content makes is apparent because humans will notice increased fatigue and reduced concentration. In rooms with high occupancy such as conference rooms and theatres, negative effects become all the more evident.

Technical specs:

• Super large LCD simultaneously display of CO2 level, Temp., relative humidity, Date and Time.
• Six (6) smiley icons indicate indoor air quality levels (350/450/700/1000/2500/5000ppm), easy to understand CO2 concentration.
• Stable NDIR sensor for CO2 detection
• Hi alarm threshold is selectable, easy to reset default setting by pressing one button. Automatic Baseline Calibration (ABC)
• Audible warning for high CO2 concentration
• Visable LED meter status.
