PCE Instruments PCE-CMM 5-ICA CO2 detector 400 - 5000 ppm Datalogger function, Thermometer Calibrated to ISO standards

The CO2 meter is designed for use on a desk and measures the CO2 content in the air shown on a large LC display. The CO2 meter can be used to effectively monitor the ventilation behavior in offices, classrooms, lecture theater and other rooms.

The CO2 meter checks the quality of the room air beyond the CO2 content. If the CO2 concentration is below 1000 ppm, the room 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 mixed with fresh air again and again. The CO2 meter indicates air quality as numerical measurement and as traffic light indicator. The CO2 content of the last five hours can be shown on the display by pressing a button.

Besides the CO2 measurement function, this CO2 meter is also equipped with a sensor for temperature and humidity. Air quality monitoring sensors are subject to different requirements than those used in industrial or scientific laboratory applications. The focus is therefore on sensor properties such as high long-term stability, low maintenance costs and low energy consumption. The CO2 meter fulfills these with its NDIR sensor. The non-dispersive infrared (NDIR) absorption measurement enables accurate and long-term stable measurements at an absolute measurement range of up to 5000 ppm.
