PurpleAir PA-II-FLEX

General Description

The PurpleAir PA-II-FLEX sensor is an air quality monitoring device that provides real-time measurements of PM_1.0, PM_2.5 and PM­₁₀ mass concentrations and environmental parameters such as temperature and relative humidity. Data can be accessed and downloaded on the PurpleAir website.

Principle of Operation

The PurpleAir PA-II-FLEX sensors use dual Plantower PMS6003 laser particle counter, where laser beams detect particles by their reflectivity. These sensors count suspended particles in sizes of 0.3, 0.5, 1.0, 2.5 and 10 μm. These particle counts are processed by the sensor using a complex algorithm to calculate the PM_1.0, PM_2.5 and PM₁₀ mass in μg/m³. The PMS6003 sensors come factory calibrated.
