Environmental Carbon Dioxide Monitor and Data Logger l arge LCD Displays CO2 Level, L Temperature, Relative Humidity, Calendar (Y/M/D) and Time l ix (6) Smiley Icons Indicate S Indoor Air Quality Levels at (350/450/700/1000/2500/5000 ppm) l Stable Ndir Sensor for CO2 Detection l Programmable High Alarm l Manual 400 ppm Calibration l Audible/Visible Led Warning for High CO2 Concentration l Heat Index/Wbgt Temperature Calculation 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. Non-Enforced Reference Levels* 250 to 350 ppm – Background (normal) outdoor air level 350 to 1000 ppm – ypical level in occupied spaces with T good air exchange 1000 to 2000 ppm – Level associated with complaints of drowsiness and poor air 2000 to 5000 ppm – Levels associated with headaches, sleepiness and stagnant, stale, stuffy air; poor concentration, loss of attention, increased heart rate and slight nausea may also be present >5000 ppm – xposure may lead to serious oxygen E deprivation resulting in permanent brain damage, coma and even death AQM-102 shown smaller than actual size.
