Ventilate only when necessary

AERO CO2 continuously analyzes the CO2 level and visually alerts the occupants when it is time to ventilate to renew the interior air.

Thanks to its LoRaWAN wireless IoT communication module, ambient data can be accessed remotely, simply from a smartphone or computer screen*.

*optional subscription fees may apply.


Reliability of CO2 measurements

The measurement of the CO2 level is a reliable indicator of the good renewal of the air in a closed space.


AERO CO2 is equipped with a latest generation NDIR type CO2 sensor. The accuracy of the CO2 detector measurements has been validated by an independent COFRAC approved laboratory.


No maintenance is required and there is no risk of drift of measurements over time.  AERO CO2 integrates an automatic and weekly recalibration function of its CO2 sensor.

A manual calibration of the CO2 sensor is also possible.

Easily install your sensors

AERO CO2 can be installed on the wall thanks to its anti-theft mounting base or free-standing, on a table, so that it can be moved easily from one space to another.

AERO CO2  runs on mains power via USB-C power for simple and easy integration into any work environment.


A healthier indoor environment

The Green / Orange / Red indicator light simplifies the immediate understanding and implementation of actions adapted to the air renewal.


The detector's indicator light is fully configurable. 

Simply download the free App.Nexelec application from the Google Play Store on your Android smartphone and configure your detector in "contactless" NFC to change the thresholds taht trigger the indicator light.


As standard, the light turns Orange at 1000 ppm and Red at 1700 ppm.
