AIR QUALITY SENSORS

Air Quality Transmitter AQT400 Series - for Measuring Pollution Gases and Particles

 

Vaisala Air Quality Transmitter AQT400 Series measures the pollution content of ambient air. The series consists of two products, AQT420 and AQT410.

 

Features

  • Measures four most common urban air pollutants: NO2, SO2, CO, and O3
  • Intelligent algorithms that compensate for environmental conditions and for the aging of the sensor element
  • Compact design; easy to deploy in the field
  • Low power consumption (typically 0.5 W)
  • Wireless Internet connection with Vaisala Multi-Observation Gateway MOG100
  • RS-232 and RS-485 interfaces for local connectivity (such as Modbusâ support)
  • Easy integration and open API

 

Applications

  • Urban air quality networks
  • Industrial emission monitoring
  • Safety monitoring
  • Roadside monitoring
  • Building automation
  • Air quality research

 

New Value in Air Quality Measurements

AQT400 series revolutionizes air quality measurements. It offers totally new value for money by providing a near reference measurement performance.

 

With default configuration, AQT420 and AQT410 measure the most common gaseous pollutants: nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3). In addition to all this, AQT420 also measures particulate matter (PM2.5 and PM10) in the ambient air.

 

The measurement performance of AQT400 series is based on proprietary advanced algorithms that enable parts per billion (ppb) measurements at an affordable price by using electrochemical sensors. The algorithms compensate for the impact of ambient conditions and aging on the sensor elements and remove the need for costly gas sampling and maintenance equipment.

 

Easy to Deploy in Networks

AQT400 series is 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. The measurement data is sent wirelessly to a web-based database with a gateway solution or is available locally through a serial interface. Depending on local conditions, AQT400 series device has a maintenance and calibration interval of 12 ... 24 months.
