Digital Hygrometer Thermometer Indoor/Outdoor Hygrometer 4PC | Mini Size,LCD,℉/℃ Conversion,Fast Response, Outdoor Thermometer with Humidity for Reptile Greenhouse Cellar 3D Printer

These worked great for our greenhouse this spring! Easy to set up, install, use, and read! Great product for the price.

I bought this 2-pack for our Grove snail habitat, and they are exactly what I needed. They arrived ready to go and were working perfectly right out of the box. I really appreciated that they came with extra batteries and extra sticky dots—it made mounting them inside the enclosure so much easier! They are small enough that they don't take up much space, but the display is easy to read. It’s great for keeping a close eye on the temperature and humidity levels to keep the snails happy. Excellent value for the price!

Perfect size for me and my use. I got these for my isopod bins and they are very helpful. It helped me figure out that my humidity is a little too high and my temperature is perfect :) It came with batteries in them already and an extra battery for each hygrometer. It also came with a large foam sticker, but I opted for a small glue dot so I can easily view the reading.

These things work pretty well. I bought two, one to sit inside my AMS and one to sit outside, so i could compare the AMS internal properties to the room properties. The two devices seem to be pretty consistent in their readings. I did however notice that the AMS reports a higher humidity than this meter does. The devices arrived with batteries in them, but unlike other products that have batteries pre-installed, these didn't have a pull tab to break the circuit until use, so the batteries are somewhat depleted (i presume, based on the dimness of the displays). No biggie though - they accounted for this and included extra batteries (i haven't installed them yet though). I plan to buy a few more of these and put them into my filament storage cases.

I picked up this 6-pack to monitor overflow cigars that I keep temporarily stored in airtight Tupperware containers. I tend to buy cigars in larger quantities, so sometimes they sit before I make room in my humidors. These little hygrometers are perfect for that purpose. They’re small, easy to tuck inside containers, and give me a quick snapshot of temperature and humidity. They’re not lab-grade precision, but they’re close enough to keep an eye on things and make sure nothing is drifting too far. For the price, getting six of them is a no-brainer. If you need simple, affordable monitoring for secondary storage, these do the job.

Works as expected and well. Common size battery I already have on hand so easy to replace. I am using them for my Bambi 3d Printer and they greatly help track the temperature and humidity.

Used to measure the temperature and humidity levels for my gargoyle gecko. Looks to be pretty accurate with the readings. I like how compact it is and it fits well in the enclosure.

This is the 3rd time I have purchased the Hygrometers. They are perfect in size and easy to use. The display is pretty big and the numbers are clear to see. I used them for my filament storage containers. They look great. The set also comes with a spare button cell battery and double-sided adhesive tape. They are also pretty accurate with temp a humidity readings. The seller also ships fast which is a huge plus. If you are in the market for hygrometers, these are definitely worth the price and investment.

They’re very helpful, I use it in my jumping spider terrarium.
