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® comes standard with:
Black carbon sensor
Relative humidity/Temperature sensor
16 Gb SD card + MicroUSB cable + Charger
Magnetic dust/moisture cover
10 replacement filter tabs
Optionally, the ObservAir® includes up to two gas sensors, one wireless communication module, and GPS to fit your AQ application. See details below.
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 filter life.
Filter replacement is a breeze!
Basic Enclosure for Outdoor Deployment
Our Basic Enclosure is fully weather sealed and insulated for extended outdoor deployments. It easily mounts anywhere, and locks securely. A removable AC cord and integrated DC charger power the sensor from a wall socket. Using this enclosure, the ObservAir® can operate in rain and other inclement weather, but operating limits (temperature/ humidity) must still be respected. The insulation is removable to accommodate operation in warmer locations.
Need to measure more? We can customize the ObservAir® to fit your unique application. We can add nearly any digital sensor to our modular platform, such as a weather station, additional AQ sensors, accelerometer, 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 enclosures, remote power solutions, and data processing software.
