ObservAir Series

All ObservAir units are centered around our patented aerosol absorption photometer to monitor black carbon pollution. Particulate matter is collected on a disposable filter tab that must be replaced every ~2 to 20 days (filter life depends on the sensor configuration and sampling conditions - see here).


Each ObservAir carbon analyzer comes standard with:

  • Black carbon sensor 

  • WiFi/Bluetooth/USB communications

  • Relative humidity and temperature sensor 

  • 16 Gb SD card + MicroUSB cable + Charger

  • Magnetic dust and moisture cover 

  • 10 replacement filter tabs 


Optionally, the ObservAir includes up to two gas sensors with available options including O3 (ozone monitors), NO (nitric oxide monitors), NO2 (nitrogen dioxide monitors), SO2 (sulfur dioxide monitors), CO (carbon monoxide monitors), and H2S (hydrogen sulfide monitors). Other ObservAir options include a wireless communication module and GPS to fit your AQ application. For more details about our air quality measuring device, seebelow.

Replacement Filter Tabs

The ObservAir's aerosol absorption photometer collects particulate matter on disposable filter tabs that only cost $1 USD each and take < 30 seconds to swap out. Filters must be replaced every ~2 to 20 days, depending on the average black carbon concentration sampled and flow rate setting. Filter life is shown here for various settings and applications. The ObservAir manual has instructions for setting sample flow rate to maximize the carbon analyzer's air filter life. 

Filter replacement is a breeze!

Basic Enclosure for Outdoor Deployment

Outdoor Air Quality Monitoring System Enclosure

Our Basic Enclosure is fully weather-sealed and insulated for extended outdoor deployments of your air quality monitoring station. It easily mounts anywhere and locks securely.  A removable AC cord and integrated DC charger power the sensor from a wall socket. Using this black carbon instrument enclosure, the ObservAir can operate in rain and other inclement weather, but operating limits (such as temperature and humidity) must still be respected. The insulation is removable to accommodate operation in warmer locations.

Custom Solutions

Custom Solutions

Need to measure more? We can customize the ObservAir carbon analyzer to fit your unique application. We can add nearly any digital sensor to our modular platform, including weather stations, additional AQ sensors, accelerometers, and more. All data is processed/logged onboard using a powerful microprocessor, and sent wirelessly to our mobile app and PC dashboard services where it can be accessed in real-time. In effect, the ObservAir can serve as a turn-key, wireless sensing 'hub'  around which to develop your specific environmental monitoring platform. We also produce custom black carbon instrument enclosures, remote power solutions, and data processing software.
