With this traffic light, the current carbon dioxide concentration in the ambient air can be measured and clearly displayed using the three traffic light colours.
The system displays its concentration in the ambient air according to CO2 thresholds: Green (ambient air OK), yellow (ventilation recommended), red (ventilation necessary), red blinking (ventilation urgently required)
Provides clear feedback on CO2 concentration
Eliminate high concentrations of carbon dioxide and aerosols in enclosed spaces based on a reliable reminder for regular intense ventilation
Ensure hygienic and productivity-friendly ambient air
Clearly visible from all positions thanks to the OmniVIEW lens
Increased safety for employees and customers
Variants & typical applications
The CO2 Traffic Light (1.000 ppm variant) is ideal for all interior spaces where people regularly spend long periods of time, such as public buildings, restaurants, shops, universities, schools and open-plan offices.
The CO2 Traffic Light (800 ppm variant) is ideal for sensitive environments such as doctors' surgeries and hospitals.
Thanks to its plug&play functionality, the CO2 traffic light can be set up quickly and easily and is immediately ready for use. The power supply is provided by the included mains adapter (230V).
Features (1.000 ppm variant)
The traffic light is green up to 1.000 ppm*
The traffic light is yellow from 1.000 ppm to 2.000 ppm
The traffic light is red from 2.000 ppm to 3.000 ppm
The traffic light blinks red from 3.000 ppm
*(The German Federal Environment Agency officially recommends ventilation from 1.000 ppm / ppm = parts per million, i.e. parts by volume per million parts by volume).
Features (800 ppm variant)
The traffic light is green up to 800 ppm**
The traffic light is yellow from 800 ppm to 1.200 ppm
The traffic light is red from 1.200 ppm to 2.000 ppm
The traffic light blinks red from 2.000 ppm

Application of the CO2 traffic light in the meeting room
Peter Eichmüller | Managing Director Communicall GmbH
"With the WERMA CO2 traffic light we can monitor the air quality in our rooms very easily and precisely. Especially in open-plan offices it is important to ventilate in time. This is signalled by the CO2 traffic light, which is highly visible. The CO2 traffic light can be placed in a different location at any time, so that it can also be used in the conference room during long meetings, for example. A perfect addition to the air purifiers we have already been using for a few months. Maximum protection for our employees."
Application of the CO2 traffic light in a production environment
Markus Bächle | Team Leader of Maintenance and Repair at the HYMER Electrical Workshop
"We simply wanted to permanently and reliably display the current status of the air quality to everyone present. WERMA was already a household name for us, after all we have been using the signal towers and the radio-based MDE system 'SmartMONITOR' for some time and are completely satisfied with these clever solutions. We didn't think twice and immediately ordered 12 CO2 traffic lights from WERMA for an initial trial run. These were put through their paces in a separate production area. The traffic lights hang centrally and somewhat higher, so that they can be easily seen from everywhere. This immediately gave everyone present a good and above all safe feeling."
