Nowadays, where health and comfort are becoming more and more important, controlling indoor air quality is becoming a priority. Therefore, carbon dioxide (CO2) meters play a key role in ensuring the safety and comfort of building users.

Why are carbon monoxide levels high?
Excessive CO2 levels can lead to dangerous consequences for the health and comfort of users. One of its main causes is ineffective ventilation. To ensure optimal conditions, it is therefore important to regularly ventilate or use air purifiers. Another factor is too many people staying in closed rooms, which leads to higher CO2 emissions from their breathing. Additionally, using inappropriate building materials, such as low-quality insulation or lack of tightness in windows and doors, may lead to carbon dioxide leaking from the outside into the interior of buildings.
What should you consider when choosing a CO2 meter?
Advanced meters are most often equipped with a thermometer, an air quality sensor, an NDIR (non-dispersive infrared) carbon dioxide concentration sensor, and a temperature sensor. When choosing a meter, pay attention to the stability and accuracy of the NDIR sensor and the use of additional functions, such as automatic calibration, which enables high measurement accuracy without the need for manual calibration, and the HOLD function, which allows the user to freeze the reading on the screen for further recording or analysis. It is good if the carbon dioxide meter can cooperate with a PC via a USB or Bluetooth interface to transfer measurement data to the computer and process them using appropriate software.
How to properly measure air quality with a CO2 meter?
Before starting the measurement, make sure that the meter is properly configured and calibrated according to the manufacturer's recommendations and that it is properly charged or connected to the power supply to avoid measurement errors.
Then place the meter in the central part of the room at a height of approximately 1.5-2 meters above the floor and away from sources of potentially contaminated air, such as heating furnaces or chemical storage areas, to obtain the most representative measurements possible. When measuring CO2 in the air, pay attention to current conditions, such as temperature, number of people present, presence of plants, intensity of heat-emitting devices and air humidity.
It is also important to regularly carry out measurements in different places and at different times of the day to obtain a comprehensive assessment of indoor air quality. The optimal level of carbon dioxide concentration indoors should be kept as low as possible, in accordance with applicable safety standards and guidelines on air quality and oxygen concentration inside buildings.
