General Introduction
 
 
Indoor Air Quality (IAQ) is measure for the quality of air in interiors, the comfortable indoor environmental quality can make people feel fresh, work efficiency and good for the health. The CO2 concentration is the important factor of good indoor air quality. People breath in oxygen and breath out CO2, nowadays people often close the windows to avoid noise and enjoy the comfort living and working environment provided by air-conditioning systems, which results in the fact that the indoor concentration of CO2 is far higher than outdoor average. With the high CO2 concentration and non- proper ventilation, people will feel headaches, dull, drowsiness, lose of concentration and correspond to the high levels of dust, chemicals and bacteria in the air.
 
 
Features
 
 
Dual Beam NDIR (Non-Dispersive-Infrared) technology is being used to measure CO2 concentration and
  improve the long term stability.
The Large LCD clearly displays CO2, Temp., Relative Humidity and real-time clock.
3-color backlight displays indicate the status of current CO2 concentration.
“HISTORY” with 3 emotions indicate the status of CO2 records up to 24 hours.
“ECO“ saving power function darken the LCD backlight (22:00pm to 6:00am).
