Envea Cairclip O3/NO2

The CairPol CairClip O₃/NO2 is a lightweight, portable sensor for measuring ozone and nitrogen dioxide in parts per billion or micrograms per cubic meter in applications such as personal exposure and indoor and outdoor air quality monitoring. It uses a micro fan to actively sample air. The CairClip can run on battery power for approximately 24 hours, but it can also operate continuously for much longer periods when plugged into a power source. To calculate the concentration of ozone, this sensor needs to be combined with the CairPol CairClip NO₂ sensor, since nitrogen dioxide concentration needs to be subtracted from the measurements of this sensor.
