Air Quality Monitor PM2.5 Bluetooth Thermo-Hygrometer Digital Hygrometer Indoor Humidity Gauge for Home Office Humidity monitor for Bedroom, Livingroom S1+

It is a nice small gadget to have around the house. It's easy to read and to charge. The only snag is that it needs to be constantly plugged in to update second by second. I do not leave it plugged in permanently but do so every other hour or so. That, I think is often enough to check your air quality or temperature.

Nice little device from temtop..always confident about the accuracy of these readings..gives me reassurance that I need to ensure my indoor environment is as it should be...health guardian for sure..thanks guys..

Very good quality. Easy to use.

Great piece of equipment for monitoring air quality I use it in our bedroom and as a result of higher values, I purchased an air purifier. Both my husband and myself have noticed a better night's sleep. Great value for money and easy to use. Displays are easy to read and it comes with easy to use instructions.

Needed to check air quality. A better product than expected, well finished and working well. Recommended.

I use this air quality monitor daily in my bedroom to check for the quality of air. I bought a pair of these devices, a slightly different one, and I like them. The engineering is good, they are robust and they're very easy to charge up as usb-c devices. In this area there are a lot of expensive devices with questionable capacities that these are good and as far as I can tell accurate

The device's readout of air quality works best 20 seconds after turning on, but unless the device is plugged in to the charger, it will not update continuously but will stop measurements after 3 minutes 15 seconds (or earlier in Eco mode) and then it will refresh very rarely. The reading sometimes spikes for a moment, so if the device freezes at that moment, you will be stuck with the wrong value for around 20 minutes. The measurement of the temperature is accurate (and does not freeze), it agrees to within 0.2C with my other thermometer. But the measurement of humidity is woefully inaccurate. I own a dehumidifier which monitors the live humidity and I also have a mechanical hygrometer and the former says the humidity now is 59% the latter says 60%, but this air quality monitor says it's 50.2%. Clearly nonsense. The customer support of Elitech UK is amazing, though

My son has quite bad asthma and this helps me keep control over the air quality in his room at night.

Junk. In a small non-ventilated room with two people smoking, it days the air quality is better than in the bedroom with open windows.

Great choice good value for money and accurate data

Das Messgerät ist jetzt seit zwei Wochen im Einsatz, es sieht gut aus. Die angezeigten Werte sind sehr perfekt ablesbar, der Akku ist immer noch "voll" laut Anzeige und die Messerwerte (Luftqualität) stimmen mit den offiziellen Daten überein. Auch die Verbindung zur App geht super einfach und schnell. Bis jetzt habe ich keinen Kritikpunkt gefunden, daher 5 Sterne.

ottimo prodotto, fa il suo dovere.

Réglages faciles, petite station pratique et précise.
