Rien a dire efficace

This monitor serves its purpose, and I appreciate the large, easy-to-read screen. However, I have an issue with the clock. It arrived set to military time, and I successfully changed it to Eastern Time by following the instructions. Despite that, the clock intermittently switches back to military time and then returns to Eastern Time. For example, it displayed 22:22 am at one point and 6:30 p.m. later. This happens throughout the day and night, and it is baffling. Rather than constantly resetting the clock, I have decided to leave it alone. After all, I did not buy the monitor for the clock.

Bon rapport qualité prix

Das Gerät ist sehr gut und die Ergebnisse zuverlässig. Preis-Leistungsverhältnis ist sehr gut und die Bedienung des Gerätes ist intuitiv.

Works as advertised. Good price

This seemed to work as expected. Easy to see and alerts when levels are dangerous. I have know way to know if it's accurate or not but at least I can see when VOC increase.

Toestel werkt goed. Instellen is deel niet zo evident maar met handleiding kunt het wel. Ideaal voor mensen die verwarmen met de houtkachel en de kwaliteit van de omgevingslucht willen meten in de huiskamer. Ondertussen ben ik gerustgesteld over die luchtkwaliteit Het toestel ligt niet constant aan maar wordt af en toe aangezet voor een meting . Prima materiaal met duidelijke display.

Boa tarde, Necessito fatura.

Not sure it's 100% accurate for "rare" sensors. Temperature and humidity are not exactly matching other devices that measure these things in my house, but what I care most was HOHC and TVOC, for which I dont have a secondary device to confirm the values, therefore I can assume they are "somewhat" accurate, still good enough indicator if I have a problem or not. Overall I am satisfied with the purchase.

The battery dies quickly and doesn't hold up, I have to leave it plugged in 24/7, other than that it's a great tool to have to keep in the home to monitor the air quality!!! Could save your live!!
