How a CO2 meter helps improving air quality
Why do you need a CO2 detector?
With the CO2 meter you can quickly and easily assess the air quality and know when it is time to ventilate.
The CO2 detector monitors the CO2 (carbon dioxide) concentration in a room. At first glance, CO2 is a natural component of air, including human breath. But the exhaled air also contains so-called aerosols, which can contain infectious viruses.
The CO2 concentration in indoor rooms is crucial for the assessment of air quality. This is all the more true when several people stay in a room for a longer period of time. The use of a CO2 meter is therefore particularly recommended when many people are in enclosed spaces. Typical areas of application are, for example, offices, schools, teaching, seminar and meeting rooms.
Improve air quality and reduce virus load
The CO2 meter contributes to health protection and also used to assess the risk of infection from aerosols. It is useful for quick assessment of indoor air quality and indicates the need for ventilation with a traffic light display and acoustic alarm signal.
Excessive CO2 concentrations can be eliminated by regular ventilation. However, this is often forgotten and recommended regular airing is rarely implemented consistently. The CO2 traffic light on the digital display or, at the latest, the acoustic signal of the device (above the critical level) clearly indicate polluted air and the need for ventilation.
What CO2 level is acceptable?
The CO2 value is measured in ppm, short for parts per million.
Outdoor air, for example, has a CO2 concentration of about 340 - 450 ppm.
The limit values for CO2 in indoor rooms, according to EN 13779, are:
- Below 800: High indoor air quality
- 800 - 1,000: Average indoor air quality
- 1,000 - 1,400: Moderate indoor air quality
- Above 1,400: Low indoor air quality
1,400 ppm is the upper limit for acceptable indoor air quality. Symptoms may include headaches and fatigue, and the virus load in the enclosed space is increased.
An even higher value is to be classified as dangerous from an air-hygienic point of view. At a maximum indoor guideline value of 1,500 ppm, ventilation is required! Above 2,000 ppm, the risk of infection with viruses also increases significantly.
Where to place the CO2 detector?
The carbon dioxide detector can easily be placed on the table or alternatively hung on the wall using the included accessories.
To be able to measure the concentration of carbon dioxide, the CO2 detector should be placed at a height of 1.0 to 1.5 metres. It is important that the device is free-standing and does not, for example, lie under the stack of papers or be painted over on the wall. This will otherwise impair the sensors that measure the CO2 concentration.
The brennenstuhl® CO2 meter can be used for up to 12 hours with the integrated battery, otherwise via power supply. Battery operation is ideal for a mobile use of the device, e.g. when you are in changing offices, meeting rooms or classrooms.
How does the CO2 meter measure?
The CO2 meter is equipped with a high-quality NDIR sensor (measuring +/- 50 ppm). The sensor measures the concentration of carbon dioxide (CO2).
Carbon dioxide is a natural component of the air and too high concentrations can be eliminated by regular ventilation. The CO2 detector shows consumers when ventilation is necessary. The CO2 detector thus helps to improve indoor air quality and reduces the risk of infection.
The result of the measurement is indicated visually. The traffic light display makes it easy to see what the value indicates about the current air quality. The traffic light display changes between green, yellow or red LED depending on the CO2 concentration. In addition, the CO2 meter emits an acoustic alarm signal as soon as the value of 1,400 ppm is exceeded.
Assess air quality with the Brennenstuhl CO2 meter C2M L 4050
Checking carbon dioxide value, temperature and humidity in rooms has never been clearer. With the help of the traffic light display and the alarm signal of the CO2 meter, the indoor air quality and the need for ventilation can be quickly assessed.
The brennenstuhl® CO2 detector is perfect for all indoor areas and closed rooms, e.g. in the home, school, office, kindergarten or public facilities.
