The AQM-102 is designed to measure CO2 concentration, air temperature and relative humidity with visible and audible alarms. This CO2 monitor is an ideal instrument for indoor air quality (IAQ) diagnosis and HVAC system performance verification. 

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 400 ppm. With each breath, humans convert oxygen (O2) into carbon dioxide (CO2). Although carbon dioxide is invisible and odorless, increased CO2 levels can cause headaches, drowsiness and a loss of the ability to concentrate or worse.
