The Vaisala AQT400 series air quality sensor is used to monitor urban gas pollutants such as nitrogen dioxide, sulfur dioxide, carbon monoxide, and ozone, as well as particulate matter PM2.5, PM10; The AQT400 series has revolutionized air quality measurement, providing an unprecedented high-value solution. Both models, AQT410 and AQT420, can measure the most common gas pollutants: nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3). In addition, AQT420 can also measure particulate matter (PM2.5 and PM10) in the ambient air. The measurement performance of the entire series is based on proprietary advanced algorithms, achieving parts per billion (ppb) measurement operations for electromechanical sensors at a reasonable cost. Algorithms can compensate for the impact of various environmental conditions and the aging of sensor components, so there is no need to purchase expensive gas sampling and maintenance equipment.
