Das Display lässt sich gut ablesen, auch aus ein paar Metern Entfernung, und sowohl dunkler stellen als auch abschalten. Die Batteriefunktion ist nur als Backup gegen Datenverlust vorgesehen. Dann läuft das Display im gedimmten Modus. Was stört ist, dass ein 1-minütiger Scan startet, wenn man das Gerät vom Strom und in einen anderen Raum trägt. Das nervt, und ich habe direkt zusätzlich ein anderes, günstigeres Gerät bestellt (und rezessiert), bei dem das besser ist, zum Einsatz in mehreren Räumen. Dieses hier bleibt stationär. Wer es trotzdem herumtragen will, kann eine Powerbank nutzen, hat zumindest bei mir funktioniert, ist aber umständlich. Für mich ist es stationär okay, weil mir die gut ablesbare Anzeige gefällt, und die gemessenen Werte plausibel scheinen.
Die CO2 Konzentration in Räumen zu messen ist durchaus nützlich. Zu viel CO2 bedeutet Schwindel oder Kopfschmerzen. Mit diesem Gerät kann man überprüfen, wie man lüftet, so dass die CO2 Konzentration in einem erträglichen Bereich ist. Der einzige Wermutstropfen: das Gerät verbraucht relativ schnell Batterien, ich empfehle es, mit einem Netzteil zu betreiben.
Das Gerät hat ein auch aus einigen Metern Entfernung gut ablesbares Display. Lüftet man, wird schnell eine geringere CO2 Konzentration angezeigt. Die Genauigkeit der Anzeige kann ich nicht beurteilen. Ich bin sehr zufrieden.
Es ist ein gut verarbeitetes Gerät mit einer attraktiven Anzeige. Es reagiert zügig und aus meiner Sicht präzise auf Veränderungen. Ich betreibe es, wie empfohlen, mit USB-Kabel am Steckernetzteil und nutze die Batterien nur als Backup. Die Anzeige der Historie hatte ich anfangs als schöne, aber unnötige Zutat angesehen, doch nach ein paar Tagen Benutzung möchte ich diese interessante Information nicht mehr missen.
Accurate
You can rely on the readings
Surprisingly accurate. I have an industrial monitoring system installed and bought this for outside of my grow area and to see how accurate these better priced readers are. The Non-Dispersive Infrared sensors ensure this little machine can read accurate levels. This is all you need for relatively accurate readings. It is tracking within 40 PPM of my more comprehensive sensor which really surprised me.
Reading is way different than professional Monitors
I bought it based on the reviews, but it was very disappointing, as I already have professional monitor / Aranet4 monitor , and this device CO2 reading is at least 200-250 less reading than the others, even after few days of testing also the Humidity and Temperature reading is very different. In addition of not having an app and just rely on the device.So I would spend a bit more ane just buy Aranet4 or something similar which give accurate readings, Having Application , and long lasting battery life.
Excellent petit détecteur ! On l'a mis à l'épreuve et il répond bien. Le graphique des dernières 24hrs est vraiment utile et le réglage du niveau sonore et de la concentration de CO2 pour l'alarme est vraiment intuitif. Je le recommande.
Handy detectors. Very easy to install and to understand.
