n Detection Focus

ü Carbon Dioxide (CO2)

Indoor CO2 level is a universal accepted parameter for the     

condition of indoor ventilation and air quality.

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

l   ABC self-calibration technology guarantees reliable CO2 measurement

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

l   Rapid response, high stability and consistency

 

ü 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.

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

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

l   Small volume, lower consumption

 

ü 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.

 

n Application

u Building ventilation systems

u Industry ventilation systems

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

indication
