QuantAQ sells two air quality sensors that measure different pollutants as detailed below.
MODULAIR
The MODULAIR measures gas- and particle-phase pollutants including:
Carbon Monoxide (CO)
Nitrogen Oxide (NO)
Nitrogen Dioxide (NO2)
Ozone (O3)
Particulate Matter (PM1, PM2.5, PM10)
It is also possible to add a Sonic Anemometer to the MODULAIR, adding wind speed (WS) and wind direction (WD).
MODULAIR-PM
The MODULAIR-PM measures particulate matter only:
Particulate Matter (PM1, PM2.5, PM10)
Both products additionally report temperature and relative humidity; however, these are internal box measurements and are not true ambient measurements and should not be used as such.
