Gas detector PCE-CMM 5
CO2 analyzer, temperature and humidity / Traffic light function 5h progress display / Battery and power adapter operation

The CO2 Analyzer is a CO2 measuring device for desktop use. The carbon dioxide 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 for checking the ventilation behavior in offices, classrooms, lecture halls, etc. The CO2 / carbon dioxide measuring device helps to ensure that, for example,  there is regular ventilation for employees in the office. The CO2 / carbon dioxide measuring device checks indoor air quality via the CO2 content. If the CO2 concentration is below 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 CO2 / carbon dioxide measuring device shows the air quality as a numerical measured value and as a traffic light indicator. At the push of a button, the CO2 content of the last five hours can be shown on the display. In addition to the CO2 measuring function, the CO2 / carbon dioxide measuring device is equipped with a sensor for temperature and humidity.

The sensors for monitoring the air quality are subject to different requirements than those in 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 is fulfilled by the indoor air quality measuring device with its NDIR sensor. The non-dispersive infrared (NDIR) absorption measurement enables precise and long-term stable measurements with an absolute measuring range of up to 5000 ppm.
