Mini Hygrometer Digital Thermometer Humidity Meter Hygrometer Thermometers Indoor/Outdoor Humidity Monitor Reptile Thermometer for Greenhouse Garden Cellar Fahrenheit(℉)/ Celsius(℃) 4 Pack

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.

Great product and supplier! They arrived on time in perfect working order! These are great for my egg incubator, accurate and reliable. Easy to switch from Celsius to Fahrenheit by simply pushing a button.

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.

Great for the money, they have a clear display that only shows humidity and temperature, they have a button to change between °F and °C, which is very convenient. I'm using them for my 3D printing equipment and filament, they are also very light, so you can put it on a stand or not, it will not take a lot of your space.

I purchased these for use in a variety of areas, but primarily for my car. They are very simple but get the job done. Easy to use and read. Great value for the price! This past summer, I left work and got about a block away before I had to pull over, due to starting to fall unconscious at the wheel. I knew it was warm in my car, but did not know it was well over 100 degrees inside. These gauges are what allowed me to figure out what happened, and give me peace of mind every time I get in my vehicle.

These are consistent and accurate. Pleasantly surprised this order showed same readings as first order. If anything they might read one percent less humidity but that is immaterial to me. Temp agrees with everything I have. Like double side tape to stick unit on underside of jar lid or whatever. Some spare batteries are included.

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