CO2/VOC Air Quality sensors

  CO2/VOC Air Quality sensors Features

Designed for real time measuring ambiance carbon

dioxide level, air quality (VOC’s), temperature and

relative humidity.

NDIR infrared CO2 sensor inside with special Self Calibration. It makes CO2 measurement more accurate and reliable.


VOC and cigarette.

High accuracy temperature and relative  

humidity measurement optional

Combined both humidity and temperature

sensors seamlessly with digital auto


Provide up to 2 or 3 analog outputs for CO2, air quality (VOC’s) and temperature or relative humidity.

With LCD or without LCD selectable


Wall mounting type with easy installation.

Modbus RS485 interface with outputs forCO2, temperature, humidity and air quality (VOC’s).

24VAC/VDC power supply or

EU standard


Indoor CO2 level is a universal accepted parameter for the    

condition of indoor ventilation and air quality.

  Non-dispersive infrared (NDIR) CO2 sensor with more than 10-year lifetime

 ABC self-calibration technology guarantees reliable CO2 measurement

CO2 range: 0~2000ppm/0~5000ppm optional

Rapid response, high stability and consistency


 Air Quality (VOC)

The air quality sensor is a mix gases sensor with high sensitivity for VOC (kinds of volatile pollutant gases) such as

ammonia, toluene, formaldehyde and cigarette smoke, alcohol, H2S, and carbon monoxide. So it is very suitable to detector the general indoor air quality in real time and long term. It responds quickly to any change of the concentration of such gases.

 Semi-conduct mix gases sensor with 5~7 years life time

High sensitive to volatile gases like ammonia, toluene, formaldehyde, cigarette smoke, alcohol, H2S, etc.

Small volume, lower consumption


Temperature and humidity

Combined digital temperature and humidity sensor with high accuracy and stability. It also has compensation to

CO2 and air quality which makes the measurements more accurate by minimizing environmental effects.



 Industry ventilation systems

 Airport, train station, shopping mall, office, classroom and other public places for air quality measurement and
