2 Pack Mini Digital Hygrometer Gauge Indoor Thermometer, LCD Monitor Temperature Outdoor Humidity Meter for Greenhouse Jars Incubators Guitar Case, Fahrenheit (℉) or Celsius(℃)

Muy precisos y vienen con baterías nuevas. Funcionan muy bien y son sumamente confiables.

good and handy, its not so precise but serves the prupose and justifies the price. I kept two of these devices next to each other and there is 1% difference in humidty and 0.5% difference in temprature reading of both devices. Overall its good.

It does exactly as advertised. There's a four pack and in my opinion it's a remarkably cheap price for what it does. It works instantly out of the box. I've had them for a few months now and there are no issues so far. I keep one in my bedroom to tell me how humid the area is in there because I've had a lot of bloody noses recently when I wake up. And I keep one and my 3D printer room so that I know how dry it is in there. The display is very clear and easy to read. It is about the size of a 50-cent piece in circumference. Super awesome device for how cheap it was.

Great little hygrometers! Tested accuracy by using another hygrometer I had and it was on point. I use these in reptile cage and also in my incubators for chicken egg hatching.
