Wöhler CDL 210 CO2-Data logger

The Wöhler CDL 210 CO2 data logger and the Wöhler CDL 110 data monitor are CO2 monitors (also known as CO2 traffic lights) for continuous monitoring of the carbon dioxide concentration (in ppm) and other indoor air quality factors.

  • CO2 monitor with temperature and humidity display
  • Large carbon dioxide (CO2) measuring range up to 9,999 ppm by true infrared CO2 measurement (NDIR)
  • Display of CO2 concentration, temperature and humidity on the large display
  • Accustic and visual alert when the preset carbon dioxide concentration is exceeded
  • CO2 data logger with adjustable log rates (Wöhler CDL 210 only)
  • Protection against data loss in case of power failure (Wöhler CDL 210 only)
  • Wöhler indoor climate software for reading out and evaluating the measured data (Wöhler CDL 210 only)

The CO2 monitor is ideally suited for monitoring the CO2 concentration in buildings. The CO2 content is crucial for determining the indoor air quality and helps to optimize one's own ventilation behavior. Air temperature and humidity are also displayed and support you in a problem analysis (such as discomfort, humidity, mold, concentration problems).

CO2 measurement of ambient air

In addition to oxygen, room air also contains other gases such as carbon dioxide (CO2) as well as bacteria, fungal spores and aerosols. The CO2 content is an indicator for the quality of the room air. This gas is produced during the combustion of fossil fuels and also in the organism of living beings. Humans breathe out aerosols and CO2 continuously.  When people stay in a closed room, the composition of the air inevitably changes when they exhale. A high CO2 content in the air leads to lack of concentration, tiredness and headaches. In a good indoor climate, the CO2 concentration should be below 1,000 ppm. Natural fresh air contains about 400 ppm CO2. By frequent ventilation, not only the CO2 content is reduced, but also the virus-laden aerosols in the room air are diluted.  This can prevent the spread of viruses (e.g.: the Corona Virus Sars-CoV-2) in closed rooms.
