Vaisala Air Quality Transmitter AQT400 Series revolutionizes air quality measurements. It offers totally new value for money by providing a near reference measurement performance. AQT410 measures the most common gaseous pollutants nitrogen dioxide (NO2), sulphur dioxide (SO2), carbon monoxide (CO) and ozone (O3 ) with default configuration. AQT420 measures all this plus Particulate Matter (PM2.5 and PM10 ) in the ambient air. The AQT400 Series measurement performance is based on proprietary advanced algorithms that enable ppb measurements at an affordable price using electrochemical sensors. The algorithms compensate the impact of ambient conditions and aging on the sensor elements and remove the need for costly gas sampling and conditioning equipment.
