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

Great product. Works wonderful for my PLA and PETG filament storage keeping them at 10% Humidity. Accurate, easy to see and no issues. All 6 are in different containers and they all show same results. Love it. Great price for the value.

Alright, so a lot of people have written reviews for these little hygrometers and it doesn’t seem that a good majority of folks are using these for their cigar humidors. I’ll go ahead and let folks know that I bought the specifically for my desktop humidor. And I want to say that that so far in the week or so I’ve had these units. They seem to be working perfectly. First thing I did was do a humidity test and calibration using a BOVEDA calibration kit see picture below. These two little hygrometers consistently read at 75% to 76% humidity, which was right on par with what the test was. So for me, at least these units came as close to perfectly calibrated as possible right out of the box. They’re small easy to read and do the trick. Personally, I think there’s no need to go out there and buy a fancy expensive one unless that’s what you want. These two just fine for cigar humidors, and for telling the humidity wherever you may need it. Please keep in mind this is for me and my experience only your mileage may vary.

I needed a good Hygrometer the keep track of the humidity and temperature in a reptile enclosure I have with a sensitive critter, I installed this hygrometer and I was amazed at the accuracy, it’s amazing how well it works, it also came in a 6pack so I can monitor some other cages as well, the temperature gauge is very accurate as well , it’s also the perfect size to fit in a convenient area and not be in the way ,I highly recommend these for anyone in need of a good hygrometer

If you are using these to monitor your filament storage, they are incredibly practical but have a few quirks you should know about. ​ Pros: ​Perfect Form Factor: They are tiny. I was able to place mine directly in the center of the filament spool, which is the best place to measure the micro-climate of your plastic. ​ Decent Accuracy for the Price: While they might not be laboratory-grade, they are consistent. In my testing, both units in the pack stayed within 2-3% of each other. ​ Battery Life: They come with batteries included (LR44), and they last for months because the LCD pull is so low. ​ Cons/Things to Know: ​The "10% Floor": Be aware that many of these budget sensors struggle to read below 10% humidity. If your dry box is extremely well-sealed with fresh desiccant, the screen might just stay at 10% even if it's actually lower. ​Not a "Quick" Read: It takes about 10–20 minutes for the sensor to fully adjust after you close the dry box lid, so don't expect an instant drop in numbers. ​ No Backlight: They can be hard to read if your storage box is in a dark corner of your basement workspace. ​Final Verdict: For less than $15, these are a "must-have" for anyone printing PETG or TPU. They tell you exactly when it's time to recharge your desiccant packs before your filament gets ruined.

Using it in a 40gallon breeder for a Hognose. Works great, accurate, came with extra batteries, easy to see the screen even without my glasses on.

I picked up this 2-pack hygrometer/thermometer to keep an eye on humidity levels in a couple different places, and they’ve been working great so far. They’re small, lightweight, and easy to place just about anywhere, which makes them really convenient for jars, storage bins, or small spaces. The display is clear and easy to read, showing both temperature and humidity at a glance. I like that you can switch between Fahrenheit and Celsius depending on your preference. The readings seem accurate as well—I compared them with another humidity monitor I already had and they were very close. I’m currently using one in a storage container and the other in a small indoor setup, and both have been consistent with their readings. For something this compact, they do exactly what they’re supposed to without any complicated setup. Another nice bonus is getting two units in the pack. It’s useful to monitor different areas at the same time, whether it’s for a greenhouse, reptile enclosure, humidor, or just general indoor humidity tracking. Overall, these are simple, reliable little meters that get the job done. If you need an affordable way to monitor humidity and temperature in small spaces, this 2-pack is definitely worth it.

Very functional , but they do not measure under ten percent Humidity. They are not designed to measure under 10% humidity.Please note that

I am very pleased with this product. It is Inexpensive, gives accurate readings and is compact.

they seem to work as expected, I paired them for days in different areas to make sure they are accurate and can say they are with each other. With another brand the temp was same witin 1 deg but the RH was 3-5% different. Don't know which is correct but relatively speaking they are ok for how I'm using them, that is to monitor 3D filament humidity. Aslo, I dont think they go below 10% RH so keep that in mind.

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.

Both are amazing fairly accurate. Just 10 times more expensive than Indian version. Size is small portable. Quality is amazing. Easy to use.

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!
