Depending on the device version, the multi-sensor measuring device records the measured quantities CO2 (0-2000/3000/5000/10000 ppm), relative humidity (0-100% r.h.) and temperature (0 ..+50°C). The CO2 concentration is visualized via an LED traffic light (green/yellow/red). The version with a backlit LCD display shows the measured values and min/max values for CO2, relative humidity and temperature and in addition, the threshold values for the 3 LEDs of the traffic light function (CO2 concentration) can be set separately in the menu. As an option, the measuring device has a piezo buzzer and / or potential-free changeover contact. The alarm threshold can be set with a potentiometer. When this limit is exceeded, the buzzer beeps every 5 seconds or the changeover contact switches. The buzzer signal is deactivated for 10 minutes or permanently if necessary using a mute button. The CO2 concentration is measured using a non-dispersive infrared sensor (NDIR). The humidity and temperature are recorded by a digital sensor, which guarantees a highly accurate and long-term stable measurement result. The measuring device carries out an automatic calibration at regular intervals, which guarantees long-term stable measurements. The modern room housing has a quick-release fastener, extra-large ventilation slots, thermal decoupling and much more. The measuring device can be mounted on-wall or on a flush-mounted box using screws and is ideal for use in workplaces, schools, living rooms, and medical facilities to reduce the risk of infection, e.g. To minimize COVID-19 with proper ventilation.

Display:	traffic light display for CO2 with 3 LEDs (green/yellow/red), optional LCD display with backlight on/off/auto
Automatic calibration:	The automatic CO2 calibration takes place every 7 days, this compensates for any drifts and achieves excellent long-term stability. To ensure this function, the device must be supplied with power for at least 7 days without interruption and ventilated once with fresh air (CO2 300...400 ppm) for approx. 10 minutes within this period. For the CO2 calibration, the device saves the minimum CO2 value measured during this period internally. After 7 days, this minimum value is normalized to 400 ppm CO2 and the output signal corrected accordingly. The maximum correction is limited to half of the determined drift. If the measured value falls below approx. 300 ppm, the calibration is initialized to 400 ppm. The automatic calibration can be deactivated if necessary and performed manually.
Pressure dependency:	CO2: 0,16% f. mv/hPa
Running-in time:	< 5 min
Initial operation:	After switch-on of the device follows a self-test and the tempering, which takes ca. 10 minutes depending on the environmental conditions.

Manual calibration:	The manual CO2 calibration of the output signal to 400 ppm (zero point) is started by pressing the button on the circuit board (hold it down for approx. 5 seconds until the LED flashes). Before that, continuous operation of min. 10 minutes in fresh air. The LED is deactivated after successful calibration.
