Indoor air quality measurement

Sensor referenced in the official guides of the French Ministry for Ecological and Solidarity Transition and the ADEME.

Numerous studies in recent years have shown that we spend on average more than 80% of our day in enclosed spaces exposed to many pollutants, and that indoor air is often of lower quality than outdoor air.

The Class'air sensor, designed under a CSTB (French Scientific and Technical Centre for Building) licence, measures indoor air quality and raises awareness of room ventilation according to the CO2 level.

The Class'air solution is used for measurement campaigns in a self-diagnostic process for local authorities or in a regulatory process for accredited bodies. The sensor is also an educational tool for raising awareness about lockdown, with a screen and indicator LEDs for simple and intuitive visualisation.

Simple and intuitive

The screen and indicator LEDs on the sensor allow easy viewing and raise awareness of the lockdown.


The Class'air sensor is referenced in the "Qualité de l’air dans les lieux accueillant des enfants" (Air quality in places welcoming children) guide from the French Ministry of Ecological Transition and the "Ecolair" guide from ADEME

High precision

The sensor is equipped with an NDIR technology CO2 probe and digital probes.

Data monitoring

Class'air measures and reports in an autonomous way and in real time information on the level of CO2, the temperature, the humidity and the pressure.
