Air Quality Measurements

Air pollution is the biggest environmental health risk. To address this problem – to reduce pollution and clean the air – it is important to understand where and how pollution occurs. Vaisala Air Quality Transmitters AQT410 and AQT420 are​ new, cost-effective solutions for monitoring ambient air pollution. They are quick and easy to install and maintain. Perfect for extensive and dense monitoring networks, they provide information that can directly impact our daily lives. ​​​​​​


Vaisala Air Quality Transmitter AQT410

Vaisala Air Quality Transmitter AQT410

Cost effective, compact solution to monitoring air quality and meteorological data. AQT410 is an air quality transmitter that measures up to four most common gaseous pollutants such as nitrogen dioxide (NO2), nitrogen monoxide (NO), sulphur dioxide (SO2), carbon monoxide (CO), hydrogen sulphide (H2S), and ozone (O3).

Vaisala Air Quality Transmitter AQT420

Cost effective, compact solution to monitoring air quality and meteorological data. AQT420 is an air quality transmitter that measures up to four most common gaseous pollutants such as nitrogen dioxide (NO2), nitrogen monoxide (NO), sulphur dioxide (SO2), carbon monoxide (CO), hydrogen sulphide (H2S), and ozone (O3) and weather data, such as humidity, air pressure and temperature, plus particles (PM2.5 and PM10) in the ambient air.
