2 Pack Hygrometer Thermometer Digital Humidity Meter Indoor/Outdoor Humidity Monitor Reptile Thermo-Hygrometer for Greenhouse Humidors Terrarium Jars, Fahrenheit (℉) /Celsius(℃) (2)

These humidity and temperature meters are accurate and easy to read. Setup was quick, and the readings update fast. Perfect size for small spaces and great value since you get two. They also include 2 extra batteries so it should help last a long time. There is no backlight so it hard to see at night.

Working so much better than the other ones that came with my bearded. These are reading the temps and humid more accurately. I like that they come with batteries in them and then two extra as well. They are both very easy to read. They are the perfect size and don’t take up much space. They come with an adhesive to stick to the tank and that’s holding up well. So far so good. I’d recommend these

They work as advertised, I believe they show the correct temp and humidity but I'm not sure, I have nothing to work it against, the size is small enough to not be in the way and the brightness it pretty much what you expect since they don't have a light in them. I would say if you needed to know the temp and humidity then these are worth it.

They work fine for what I need them for. I gave it 4 stars because it is not 100% accurate. If you are purchasing for a reptile tank, please invest in a heat gun as well to double check the temps.

So far these meters have performed well for the price point. Ratings appear to be fairly accurate on both temperature and humidity, based on what I can tell (checking with other meters I happen to have they are within a degree of temperature and 1-2% humidity). I'm unsure how long battery life will be, or if accuracy will continue to be good in different timeframes/temperature bands. These are nice and compact, but with a screen font size that is still large enough to read easily enough. I have them in my oversized garage to help me gauge the effectiveness of a garage attic fan (by Quiet Cool) more scientifically, so they're going to be exposed to a wide variety of temperatures and humidity. I just have them unmounted so that I can move them around if desired. I'll try to update the review if anything notable happens with the accuracy over hot summers and cold winters. Otherwise, I'm satisfied with the purchase. Bottom line: these appear to be good sensors without breaking the bank.

Very handy, I keep them for my turtle terrarium. Regularly gets misted on with a water sprayer and it still functions great. Very good for the price and the temps and humidity levels are consistent with each other so I think they are well-calibrated. The size is about as big as a half-dollar coin (larger than a quarter) but not big. And the numbers are very clear to see.

These are a perfect size for using with my 3d print set up but they are not all in sync of each other. I have 2 in the same location, right next to each other and they are 3-4% different from each other. I am using these as guesstimates rather than true humidity.

Cheap, easy, and they work great! These have slanted tabs if you're looking to enclose them in something. I use them to monitor dryboxes for 3d print filament, and they work great. They come with a battery installed and already running, so they're on when you open the box, but they also come with an extra battery for each so you actually get some bonus battery life by virtue of the first battery. They also come with some small adhesive tabs that I didn't need, but might come in handy for some users. Needed a few more after this purchase and bought from the same listing, same great quality!

I was a little doubtful but I bought them, I placed them in my cigar humidor, there are always fresh boveda 67% humidty packs in there. These hygrometers read 68%, both have the same reading. So they seem to be accurate.I like the size as well, they don't take up much space.

These are fine little devices for the price, but when they arrived, one had a completely dead battery and the other had no battery at all. Other than that they're OK for the price.

Otimo produto bonitinho chegou bem embalado, vem com 2 baterias

Mit dem entsprechenden Ausdruck für das AMS fügt es sich dort sehr gut ein und gibt wichtige Informationen über die Temperatur und die Luftfeuchtigkeit im AMS. Prima!

Muy discretos y muy efectivos
