Vaisala Air Quality Transmitter AQT420 for Measuring Pollution Gases and Particles
Vaisala Air Quality Transmitter AQT420 revolutionizes measuring air quality. It is a 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. The measurement data will be sent wirelessly to a web-based database or available locally via a serial interface.
Features
▪ Measures up to four most common air pollutants (eg. VOC, CO, CO2, NO, NO2, SO2, H2S and O3)
▪ Measures particles (PM2.5 and PM10)
▪ Basic meteorological variables including temperature, humidity and barometric pressure
▪ Extremely compact, low-cost and elegant design
▪ Low power consumption (typically 0.5W)
▪ Wireless Internet connection via an optional integrated 2/3G modem
▪ RS232 and RS485 interfaces for local connectivity (eg. Modbus support)
