Vaisala Air Quality Transmitter AQT410

Overview

Vaisala Air Quality Transmitter AQT410 measures the most common gaseous pollutants nitrogen dioxide (NO2), sulphur dioxide (SO2), carbon monoxide (CO) and ozone (O3). The AQT410 measurement performance is based on proprietary advanced algorithms that enable ppb measurements at an affordable price using electrochemical sensors.

AQT410 has been specifically designed for air quality monitoring networks in urban areas, road networks or around industrial sites and transportation hubs. Thanks to its small weight and compact size it is ideally suited for deployment even in large air quality networks.
