A healthier indoor environment

Correct ventilation of collective spaces helps to significantly improve the quality of indoor air, in particular during a pandemic.

Carbon incorporates iZiAiR , an algorithm that constantly analyzes the air you breathe and indicates to you via an indicator light associated with a color code if it is necessary to ventilate the room you are in.

Reliability of measurements

Carbon is equipped with a latest generation "NDIR" type CO2 sensor that complies with the regulations for monitoring air quality in establishments open to the public.

The precision of the CO2 detector measurements have been validated by an independent laboratory.


No maintenance required and no risk of measurement drift over time. Carbon incorporates an automatic weekly recalibration function of its CO2 sensor.

Easily install your sensors

Carbon can be installed on the wall thanks to its anti-theft mounting base or freestanding on a table, so it can be easily moved from one space to another.

Carbon does not require an electrical connection and incorporates batteries with 10 years of autonomy which covers the entire lifespan of the product. No need to continually replace batteries.
