Best Terrarium Thermometers of 2025

“I love having temperature and humidity in one unit that's easy to read. I'm really happy with it, and it looks cool!”

“This product works perfectly for tracking temperature and humidity. I had no issues at all.”

“While the double-sided sticky tape didn’t last long, I switched to Velcro for easy cleaning, and it’s been great!”

"I absolutely love this little thing! I can move it anywhere in my iguana's terrarium at any time. The digits are easy to read and it's super accurate. I've only had it not work twice, but after removing the battery, it worked perfectly again. It's way more cost-effective than sticky options that can't be reused. If you want a clean and effective way to monitor your terrarium's heat and humidity, this is the best option! The only thing I would change is to make it 100% waterproof!"

"Initially, I was skeptical about this product due to some reviews, especially regarding it getting wet and malfunctioning. However, mine got wet during a move but after I removed the battery, wiped it off, and let it dry in the sun, it was good as new and still accurate. I even bought a second one for my ball python's tank. I love that I can keep track of her humidity and heat levels accurately!"

"I was really hoping this would be a great addition to my reptile tank, but unfortunately, it turned out to be a complete waste of money. The display is small and hard to read from any distance, and the suction cup kept falling off. The temperature readings were often 10-15 degrees off from my other thermometers, which is concerning for my reptiles' health. I can't rely on something that gives false readings. The only positive is that it looks sleek, but that's not enough to make it worthwhile. I suggest finding a more reliable thermometer hygrometer."

"I've bought two of these for my leopard gecko. They're accurate and easy to read, making it simple to monitor the habitat."

"I'm using it in my terrarium and the readability is excellent. I appreciate the color coding, which allows me to see the numbers from a distance."

"The sticker works well overall. It does fall off sometimes, but it still does its job nicely."

"I've been using these in my beardies tank for 6 months now, and they provide accurate readings while still having great battery life."

"For my hermit crab tank, I found this thermometer to be easy to read and great for the price. Plus, the shipping was fast!"

"I wasn't sure if the battery came installed, but mine did. They work wonderfully, and I can see the humidity change in real time when I mist the terrarium. Couldn't be happier for $10!"

"This works perfectly to display humidity and temperature in my tank. It's a medium size and has good quality readability. I can simply set it in my tank or handle it."

"I needed this for my sun room. It doesn't steam up, requires no batteries, and the display never freezes. It's just perfect!"

"I bought this for my hermit crab. I just received it, so I'm not sure about its effectiveness yet. The quality seems a bit cheap, but I guess that's expected for the price. Also, trying to read the instructions was quite a disaster. I'll update my review later based on its performance."

"I'm really impressed with the accuracy and effectiveness of these thermometers, especially for the price!"

"I found this unit to be small and effective for my needs. It's very accurate!"

"I appreciate that I can place them directly on the glass in my bearded dragon's tank, and they hold up well!"

"I was initially skeptical about using this product in my high-moisture terrarium. However, after receiving it and setting it up, I was impressed by its quality and easy installation. The suction cup held well, and I loved that there are no messy cords anymore. It’s lightweight, sleek, and I really appreciate how visible the readings are!"

"These thermometers are an amazing value for the price. I have them positioned in different areas of my terrariums, and they work just as well as much more expensive units. The clear display is great, although reading in the dark can be a bit challenging. Still, even after extended use, they maintain their accuracy. I plan to buy more!"

"I’m really pleased with this product! I love that it uses a suction cup instead of sticky tape, which can be a hassle. One day, I even found it stuck to my snake's head, but we managed that! The readings seem accurate, and it came with a spare battery, which was a nice touch."

"I was searching for a thermometer and humidity gauge for my snake tanks and ended up purchasing three of these to try out. They were spot on compared to other external ones, so I installed them in my cages. Just a tip: have a USB brick with multiple plugs to avoid using too many outlets. The adhesive is amazing, even in high humidity, and after several months, they’re still functioning perfectly. They’re easy to read from afar and remain accurate. Definitely worth the price; I’ll be buying more soon!"

"I initially bought one and tried a different model for the other side of my box turtle enclosure, but I ended up returning the other and getting this same product. It's basic yet clear and fairly accurate, maybe only off by 1 degree at most, which isn’t a big deal for my turtles. The display is just as clear and visible as it appears in the photos!"

"I'm genuinely impressed! The LED screen size and brightness are perfect for my box turtle's terrarium. I have it positioned lower in her basking area, and she sometimes tries to attack it, but it has held on really well. The temperature accuracy seems good, and I love the simple design with a single click button. It has withstood high direct temperatures and is still very sensitive to environmental changes. Setting it up was a breeze, even for someone like me who struggles with applying screen protectors. Overall, I would highly recommend this product!"

"This has been great for my crested gecko terrarium. I really appreciate having both the temperature and humidity displayed! It has worked well for a few months, so I think the batteries are great!"

"I used these thermometers for my incubator to monitor humidity and ensure it stays accurate for the eggs. They are easy to read and use, and it's a bonus that batteries come with it. Definitely worth the money if you have reptiles!"

"While I appreciate the product, I had to give it 4 out of 5 stars due to the lack of mounting capabilities. We placed one on the warm side and one on the cool side, and they seem to be working fine with accurate readings."

“I got these for my tortoise cage and my sunroom. They seem accurate and came with sticky pads. Easy to install and a great price. I would definitely buy these again.”

“I ordered these for my crested gecko tank and really like the size and functionality. The screen is easy to read thanks to the brightness and size of the numbers, even when placed on the sides of the tank. They include double-sided tape that has been holding up great. The battery life is impressive; I haven't needed to replace them in nearly a year! I've tested the accuracy using a digital thermometer, and they were only 1 degree off. I've purchased another set for my leopard geckos because I liked them so much!”

“I should mention that one of the thermometers stopped working after four days. I tried changing the batteries, but it’s completely dead. I contacted Customer Service and am waiting for a response. Also, the thermometers don’t come with the tape as indicated in the photos, which is a bit misleading. I recommend using tape that's not too strong for easy removal later.”
