eSynic 2PCS Indoor LCD Digital Hygrometer Thermometer Temperature Humidity Meter with Alarm Clock for Home Office Bedroom Babyroom etc

If like me you want to check the humidity in a particular room, maybe due to condensation (damp), it makes sense to have two of these devices so that a second may be placed in another room for reference so purchasing two makes a lot of sense.The units have a memory function that enables you to see best worst case, this is easily reset by keeping the memory button pressed for a couple of functions. There is also a clock function and temperature reading. Batteries are also included - outstanding for the price.Out of the box the readings seemed a bit inaccurate - after a couple of hours the units seemed to settle and read more consistent relative to each other and the house thermostat, and have behaved ever since.

I bought a pair of these and left them to equalise after inserting the batteries. The temperature was sufficiently consistent between the devices, but the humidity was very different. The seller very kindly replaced the instruments very quickly and the replacement instruments work fine. A nice good value for money item with a clear display and easy to operate.

Arrived early. Easy to read.

Brilliant units, had a couple of these for a few years and they have always been consistent so when I had a new requirement for a thermometer and humidity gauge I bought another two, use them in my greenhouse to monitor temps for propagation and also in a 'hot box' for overwintering chilli plants. the original two I had I use to monitor temp and humidity for a mealworm farm as I breed mealworms for the wild birds, Robins and Wagtails love them!

Ended up getting 4 of these, one the screen went after about three weeks for no reason.The other three are working ok but do have some variance between them in terms of temperature and humidity readings. I placed all of them together next to each other in the same room and they all said slightly different things.They also seem to loose time which for a digital clock I'm not sure how that can be, but all 4 were set to the clock on my phone and over the last month or so they are all at various times and all 5-7 minutes slower than my phone now.They are a bit fiddly to set up in the first instance and it's so annoying that they make this really loud beep every time you press the button so setting them up is generally a bit of a pain.It's not exactly clear either if your setting the clock or the alarm so it was a bit pot luck at first trying to figure it out.Useful as a guide but I wouldn't say they are the most exact, but I did really only buy them as a rough guide for the humidity reading as an indicator as to when I should run the dehumidifier in certain rooms etc.

More accurate than almost all other devices I tested. Great price also, considering it includes an alarm clock.The alarm clock has a bonus feature for those who might find it useful: an hourly time signal.

Bought 2. One has just failed. Never much good at keeping time Can't get time set on the other as I have lost/mislaid instructions. Nothing logical works. Both binned.

Good size and easy to see and use. Very good value for money

Den ena fungerar som den skall, den andra slängde jag, eftersom det inte gick att stänga av larmet på den.Det finns inställningar, men dess funktion är mer av slumpmässig än funktionell.Dessutom går det inte att veta om det är klockan eller larmet man justerar...Den ena lyckades jag få att fungera nöjaktigt, den andra kunde jag komma in i inställningsläge några gånger, men efter de första gångerna så vägrar den. Och då larmet går mitt i natten, så slängde jag den.

Habe vier davon bestellt, alle vier zwei Tage nebeneinander stehen gelassen.Ergebnis: Alle vier hatten dieselben Werte angezeigt. Zwischendurch gab es bei einem mal eine Abweichung um 1% Luftfeuchte.Am Ende des Testlaufs hatten aber alle dieselben Werte, und somit ist alles top.Selbst das eine Prozent Abweichung wäre noch okay gewesen. Man muß ja immer Preis-Leistung beachten, und diese Geräte sind echt jeden EUR wert.Als Bonus ist sogar noch eine Quartz-Uhr integriert, die auch nach einem Monat noch genau geht. Außerdem ist noch ein Weckmodus mit dabei. Dieser hat zwar nur EINE einstellbare Weckzeit, aber das dürfte nicht arg schlimm sein.... bei einem Gerät, dessen eigentlicher Zweck das Messen von Temperatur und Luftfeuchte ist!Daumen hoch; Werde ich wieder kaufen, wenn ich mehr Zimmer vermessen muß/will/soll. : )

Ne ho acquistati alcuni pezzi, uno con in aggiunta il sensore per la temperatura esterna. Mi sembrano entrambi abbastanza precisi, non ho mai avuto voglia di fare una controprova con un secondo termometro, ma la sensazione è che effettivamente diano un’indicazione abbastanza accurata. A distanza di circa un anno dall’acquisto funzionano ancora alla perfezione e non hanno mai avuto problemi. Probabilmente li ricomprerei, tenendo sempre bene a mente il loro costo senza quindi avere pretese esagerate.

Funcionan bien las dos unidades. Usan pilas alcalina AAA que me parece uno de los mejores puntos a su favor. Tienen una pantalla grande y clara que se ve desde lejos y eso da más libertad a la hora de elegir un lugar idóneo para ponerlo. Tiene un reloj digital al estilo de los clásicos Casio de muñeca de hace 30 años, con las mismas opciones, me ha encantado. Puedes ponerle una alarma y/o una señal horaria que hace un "beep" a cada hora en punto. Muy fácil de manejar. El calendario que incorpora no es perpetuo, solo tiene mes y día. En cuanto a precisión de las medidas es aceptable, como dice en las especificaciones +-1 ºC. Teniendo en cuenta el precio y la cantidad de factores que pueden influir sobre la calibración de cada unidad es más que aceptable. El que quiera exactitud que se fabrique uno propio con un arduino o que mire los precios de uno profesional, que aunque sea más exacto va a estar expuesto a los mismos factores de fluctuación de medidas para el uso doméstico que se le va a dar. A mi me parece una precisión perfectamente aceptable para el precio que tiene. Volvería a comprarlos si necesitase más.

Parfait pour mon utilisation. La température indiquée est pratiquement (à 0,1C près) la même sur les deux appareils, mais acheté pour la fonction hygrométrie.Le taux d'humidité semble assez précis quand je le compare au relevé météo horaire.J'apprécie surtout les énormes chiffres bien noirs, peut être lu depuis une distance de 4 voire 5 mètres.
