Health and safety for people have become a top priority in the current situation. The CO2 traffic lights from Werma make it possible to monitor the carbon dioxide concentration. These traffic lights can be applied in enclosed spaces such as in public buildings, restaurants, shops, doctor's offices, universities, schools or open offices. With the three colours can be indicated whether the enclosed spaces should be ventilated.

The distinction is as followed:

_x000D_
• Green (Air quality is good) = <800 ppm*
_x000D_
• Orange (Ventilation is recommended) = 800 ppm - 1200 ppm
_x000D_
• Red (Ventilation is urgent) = 1200 ppm - 2000 ppm
_x000D_
• Blinking red (Danger for health) = >2000 ppm
  *ppm = (parts per million) i.e. number of parts per million parts
