This Carbon Dioxide (CO2) Monitor is used to measure CO2 Concentration, Air Temperature and Relative Humidity with visible alarm. It is an ideal for Indoor Air quality ( IAQ ) diagnosis.It can calculate dew point and wet bulb temperature in second. It can also had TWA ( Time Weighted average 8 hours), STEL (short-term exposure limit in 15 minutes) reading display and the unit can be wall-mount or desktop.

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, human convert oxygen (O2) into carbon dioxide (CO2). Although carbon dioxide is invisible and odorless, an increased CO2 content makes is apparent because human will notice increased fatigue and reduce concentration.

It complies will all essential health and safety requirements set out in European Directives (CE marking). Plus all parts are made in and manufactured in Taiwan.


  • Super large LCD simultaneously display CO2 level, Temperature, Relative Humidity, Calendar (Y/ M / D) and Time (clock)
  • 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 concentration

This product uses NDIR technology for its CO2 sensor. This can only used in non-condensed areas. Not recommened for areas with huge temperature variation (high temp to low temp - cold to warm or to hot place or vice versa).

It is used only at places with constant temperature. Warranty does not cover when it is use in condensed areas.
