PAS-AF300 is the flagship model of Sapiens Portable Air Station (MAS) series products for high-performance and long-term portable air quality monitoring with integrated autonomous data quality control capabilities. The product can measure criteria air pollutants including particulate matters (PM2.5, PM10), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2) with near reference data quality under all weather conditions. Other important air pollutants including nitrogen monoxides (NO), total volatile organic compounds (TVOC) and carbon dioxide (CO2) are optional.
PAS-AF300 is equipped with the patented Pair Differential Filter (PDF) sensing technology with continuous tracking of virtual baseline for the gas sensors signals. Autozero functions are also enabled to track the long-term drift issues for both gas and PM measurements. Data transmission to designated Sapiens cloud server or user designated server through API and direct TCP links are optional.
