Mini 3 in 1 NDIR CO2 Desktop Monitor

Indoor Air Quality (IAQ) is a measure of the quality of air in interiors.

Carbon dioxide monitor for the home, school classroom, office, restaurant, fitness centre

Comfortable indoor environmental quality can make people feel better, more efficient and is good for your health. CO2 concentration is a key factor of good air quality. People breathe in oxygen and breathe out CO2, nowadays people often close the window to avoid noise and enjoy the improved living and working environment provided by air-conditioning systems, which may result in the indoor concentration of CO2 being higher than outdoor average. With elevated CO2 concentrations and poor ventilation, people may feel headaches, dull, drowsiness, loss of concentration and may also lead to high levels of dust, chemicals and bacteria in the air.




Indoor air quality monitor features

  • Dual Beam (NDIR) (Non-Dispersive-Infrared) technology is being used to measure CO2 concentration and improve the long-term air stability
  • The large LCD clearly displays CO2, temperature, relative humidity and real-time clock
  • 3-colour backlight displays indicate the status of current CO2 concentration
  • “History” with 3 emoticons indicate the status of CO2 records up to 24 hours
  • “ËCO” saving power function darkens the LCD backlight (22:00pm to 6:00am)
