CO2 measurement - indoor air quality

With the new FYAD 00-CO2Mx carbon dioxide sensor, the sophisticated ALMEMO® system offers an accurate and traceable measurement for assessing indoor air quality

In addition to the CO2 content, the new sensor measures the temperature and air pressure for automatic measured value compensation. The accuracy for CO2 measurement is +/- 50 ppm +/ 3% of the measured value. The concentration of CO2 content in the room air is responsible for the quality of breathing air in the room. A too high CO2 content reduces the performance. To reduce aerosol-borne infection risk, various studies recommend continuous monitoring of room air and appropriate ventilation behavior. However, uncontrolled, frequent ventilation can also significantly worsen indoor air quality. When outdoor temperatures are below zero, the indoor air becomes significantly drier and respiratory irritation occurs more easily. It is recommended to check not only the CO2 content but also the humidity and the air temperature. To evaluate the thermal comfort at the working or learning place, additional series of measurements of the operative temperature (globe temperature), room temperature and air flow are recorded. All relevant sensors can be connected to ALMEMO® measuring devices. Regardless of the room air quality, when wearing respirators, attention must be paid to the rebreathing of carbon dioxide, which is why the recommended duration of wearing certain respirators is regulated by occupational health and safety law. Fresh air has a CO2 content of about 300 ppm, while exhaled breathing air has between 40,0000 and 50,000 ppm.
