Luftqualitätsmessgerät 18 In 1 Co2 Tvoc Hcho Pm2.5 Pm10 Innenraumtemperatur- Und Luftfeuchtigkeitsmessung Batteriebetrieben, Datenspeicherung Lcd-display Für Zuhause

Multifunctional air quality monitor – This 5-in-1 air quality meter can detect the concentration of carbon dioxide in the air as well as HCHO, TVOC, temperature, and humidity. It is frequently used indoors and can be installed in busy areas such as restaurants, kindergartens and schools, social facilities, and cars. Automatic alarm system – When the CO2 concentration exceeds 1000 ppm, the digital CO2 meter formaldehyde detector TVOC HCHO monitor sounds an alarm in the room to remind you to ventilate the indoor environment in a timely manner. This is your practical health assistant. 1-second update: The CO2 meter carbon dioxide alarm with formaldehyde detector for air quality monitoring can update the system in real-time for 1 second and instantly recognize air quality without calibration, making it convenient and practical. Accurate detection: The powerful analysis chip is used to accurately recognize the weak current produced in the electrochemical reaction process of the CO2 detector, thus enabling more accurate detection. The CO2 monitor calibrates for 120 seconds every time it is switched on. Place the alarm in a well-ventilated area during this process. If the detected data is inaccurate, try restarting your device.
