Description

Air quality measuring device for CO2 (carbon dioxide), temperature and humidity / traffic light function 5h History display / battery and mains operation The room air quality measuring device is a CO2 measuring device for the desktop operation. The room air quality meter measures the CO2 content in the air and shows the measured value on a large LC display. The CO2 content in the air is an important measure to check the ventilation behavior in offices, classrooms, lecture halls, etc. The room air quality measuring device helps to ensure that, for example, employees in the office ventilate regularly. The measuring device checks indoor air quality over the CO2 content. If the CO2 concentration is less than 1000 ppm, the indoor air quality is optimal. Good indoor air quality helps to promote concentration. It is also ensured that the aerosol concentration in the air is low, as the aerosols are repeatedly mixed with fresh air. The room air quality meter displays the air quality as a numerical measurement and as a traffic light indicator. By pressing a button, the CO2 content of the last five hours can be displayed. In addition to the CO2 measurement function, the room air quality measuring device is equipped with a sensor for temperature and air humidity. The sensors for monitoring air quality are subject to different requirements than those for industrial or scientific laboratory use. The focus is therefore on sensor properties such as high long-term stability, low maintenance and low energy consumption. This fulfills the room air quality measuring device with its NDIR sensor. The non-dispersive infrared (NDIR) absorption measurement enables accurate and long-term stable measurements with an absolute measuring range of up to 5000 ppm.
