In today's world, where health and comfort are becoming increasingly important, indoor air quality control is becoming a priority. Therefore, carbon dioxide (CO2) meters play a key role in ensuring the safety and comfort of building occupants.

Why are carbon monoxide levels high?
Excessive CO2 levels can lead to dangerous consequences for the health and comfort of users. One of the main reasons for this is ineffective ventilation. To ensure optimal conditions, it is therefore important to regularly air or use air purifiers. Another factor is too many people staying in closed rooms, which leads to greater CO2 emissions from their breathing. In addition, the use of inappropriate building materials, such as low-quality insulation or lack of tightness in windows and doors, can lead to the leakage of carbon dioxide from the outside into the interior of buildings.
What to consider when choosing a CO2 meter?
Advanced meters are most often equipped with a thermometer, air quality sensor, NDIR (non-dispersive infrared) carbon dioxide concentration sensor, 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 allows for 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 when the carbon dioxide meter has the ability to work with a PC via a USB or Bluetooth interface to transfer measurement data to a computer and process it using appropriate software.
How to properly measure air quality with a CO2 meter?
Before taking a 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 center of the room, about 1.5-2 meters above the floor and away from sources of potentially contaminated air, such as heating stoves or chemical storage areas, to obtain the most representative measurements. When measuring CO2 in the air, pay attention to the 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 measure in different locations and at different times of day to obtain a comprehensive assessment of indoor air quality. The optimal level of indoor carbon dioxide concentration should be maintained as low as possible, in accordance with applicable safety standards and guidelines for indoor air quality and oxygen concentration.
