It works
I bought the device to check for co2 levels inside my home. The instructions says that it should indicate 400ppm outside, and my test indicated 408ppm which is very close (the device could be recalibrated if necessary). The meter is slow reacting so you will need to leave it for about 10 min on a location in order to get a more accurate reading. So in summary, it has helped a lot in determining the areas that need more ventilation. The cons are the design and labels of the functions is confusing, to the point that you will need the instructions in hand to operate if you don't know how to use it. Also, it is very slippery so make sure is left on a flat surface and never up. Providing you can live with that, this meter accomplish it's function and given the price, I would definitely recommend it.

INCREDIBILE
È preciso. Confrontato con uno strumento professionale la misurazione è analoga, non solo per la CO2 ma anche per temperatura e umidità relativa. Ben rifinito comoda valigetta istruzioni in inglese. La ritaratura avviene per la CO2 con azzeramento a valori definiti, cosa non facile, ma a quel prezzo lo si può anche comprare nuovo considerando che costa meno di un decimo di un apparecchio standard.

Buen sensor, tipo NDIR.
Sensor NDIR, buena precisión y sensibilidad en las medidas. Lo uso en un centro escolar. Nos está ayudando a saber que es importante crear corrientes de aire dentro del edificio para poder tener valores inferiores a 600 ppm (recomendación actual de los expertos en aerosoles, para garantizar que el aire que respiramos no está demasiado viciado y, por lo tanto, aumente el riesgo de contraer covid). Lo recomiendo, y debería ser de uso habitual en espacios cerrados donde compartan aire muchas personas.

Das Gerät funktioniert einbahnfrei.
Die Beschreibung im Internet trifft genau zu. Das Gerät ist vermutlich für Handwerk, die in Kanälen oder ähnlichem arbeit. Funktioniert aber auch bestens, um die Raumluft zu kontrollieren. Es ist, wie beschrieben, nicht dauernd eingeschaltet, sondern schaltet sich nach einiger Zeit ab. Ansonsten läßt sich der C02-Wert gut ablesen. Eine Messung im Freien hat gezeigt, dass das Gerät genau funktioniert. Wir sind jedenfalls zufrieden.

Je recommande l’appareil et suggère au fabricant de vendre une version valise «full accessories »
Excellent rapport q/p - mesure précise très sensible - nombreuses options - j’ai commandé le cd de software + le cable rs232 - dommage qu’ils ne sont pas compris dans la valise ainsi que l’alimentation secteur - j’aurais payé plus pour avoir l’ensemble complet immédiatement - le mode d’emploi est en anglais facile , tant pis pour les incultes à la langue de Schakespeare - l’alimentation 9V (achetée) permet un suivi continu 24h/24
