Vaisala Air Quality Transmitter AQT420

For Pollutant Gases and Particulate Matter Cost-effective AQT420 is an air quality transmitter that measures up to four most common gaseous pollutants (NO2, SO2, CO, and ozone O3) and weather data, such as humidity, air pressure and temperature, plus particles (PM2.5 and PM10) in the ambient air. Features  • Measures up to four most common air pollutants NO2, SO2, CO and O3.  • Intelligent algorithms that compensate for aging and environmental conditions  • Compact design, easy to deploy in the field  • Low power consumption (typically 0.5W)  • Wireless Internet connection with Multi-Observation Gateway  • RS232 and RS485 interfaces for local connectivity (eg. Modbus support)  • Easy integration and open API Key Benefits • Open API  • Cost-effective  • Easy to install, deploy, and maintain   • Thanks to its small weight and compact size, it is ideally suited for deployment even in large air quality networks.
