New value in air quality measurements

The supplementary air quality measurement of AQT530 modernizes the way air quality can be monitored. It offers totally new value for money by
measuring the most important pollutants in one compact package. AQT530 is available in different models, and configurations can be selected based on the needs.

State-of-the-art technology

For gas measurements AQT530 utilizes industry standard electrochemical gas sensor technology. By using proprietary advanced algorithms, individual factory calibration, and improved humidity robustness, parts per billion (ppb) concentrations at different environmental conditions can be
measured reliably in one compact package. Algorithms compensate for the impact of ambient conditions and aging of the sensor elements, removing the need for costly gas sampling and equipment.
Particles are measured with a state-ofthe-art proprietary laser particle counter (LPC). Single particles scatter light and based on the scattered intensity and number of pulses detected, the particle sizes and mass concentrations are calculated.

Easy to deploy in networks

AQT530 is specifically designed for air quality monitoring networks in areas with traffic, road networks, or around
transportation hubs.
Thanks to its small weight, compact size, and good precision it is ideally suited for deployment especially in large air quality networks. The measurement data can be sent wirelessly to a web-based database with a gateway solution and it is also available locally through a serial
interface.
AQT530 can be paired with Vaisala Connected Compact Station BWS500 to provide a professional-grade complete network solution with best-in class accuracy and reliability.
