DOQAUS Digital Hygrometer Indoor Thermometer Humidity Meter Room Thermometer with 5s Fast Refresh Accurate Temperature Humidity Monitor for Home, Bedroom, Baby Room, Office, Greenhouse, Cellar (Black)

Low price and does what I needed.
It is small but does the job. Also has a magnet on the back so it will stick up itself as well has an easel support.

Convenient, small, versatile
This is a great little tool to have if you work with resin! I’ve always worried my craft room might be too humid or not warm enough for curing, and this takes out all the guesswork.It was ready to go right out of the box. I just pulled out the little battery tab, and it instantly turned on and started reading the room. Switching between Celsius and Fahrenheit is easy with the small button on the back. The humidity display even has a tiny face that changes with the comfort level, which is such a nice touch.It’s smaller than I expected (about 2.25” tall and 1.75” wide), but that actually makes it even more convenient in a room that’s jam packed with tons of craft stuff. It has a strong magnet, a slot for hanging, and a small kickstand, so you can stick it on metal, hang it on a wall, or prop it on a shelf. The screen came protected with a soft plastic cover and looks clean and clear.It’s not just useful for resin work either. It would also be great for reptile or amphibian enclosures, or for keeping a baby’s room at the perfect temperature and humidity. For the price, this is an excellent buy. Super easy to use, as far as I know it is accurate, and it’s very convenient to use.

Check the size
Read the size of this. I didn’t. It’s pretty small, however it seems to work well. Not disappointed in it I just expected something bigger. I have a small place so it doesn’t take up much and doesn’t stick out.

Once re-installed it’s been great.
Quite happy with it now. I keep the display in next room but still close to the probs. Both probs are in a freezer in garage. I didn’t put one in the refrigerator because the refrigerator has its own internal alarm system, so I put both in the dedicated freezer. That way, I can see if the 2 match-up and help confirm accuracy. And both are within 3 degrees of each other — maybe 4 at most. The display gets a very strong signal. Alarm can easily be heard next room over, but probably not other side of house. I gave 4 instead of 5 stars because when I first set it up the 2 probs differed markedly and clearly weren’t accurate. So I got online and did a chat. On the chat they said to re-do the installation. I don’t see these instructions on the accompanying information or on-line which is why I took away one star. (At the end of this I will included those instructions.). That solved the problem. Programing/varying alarm tolerances and turning alarm for each unit off and on is easy once you understand how to do it. So just beware that you might need to re-install. But once done I really like it. Here’s re-install instructions: 1. Bring all 3 units together, side-by-side.2. Remove all batteries from all 3 units and change to a new, matching ABC channel.3. Reinstall batteries in the thermometer display unit first.4. Reinstall batteries into sensor #1.5. Reinstall batteries into sensor #2.6. The display unit should read temperatures from both sensors almost instantly. Please allow at least 20 minutes for the units to adjust to their surroundings before comparing temperature readings.

Me encantó, me da la temperatura ambiental y la humedad de los cuartos ! Excelente compra
