PAIZOO Fish Tank Digital Thermometer Accurate LED Display to ±0.9°F Tank Thermometer Aquarium Temperature Measurement Suitable for Fish, Axolotl, Turtle or Aquatic

This PAIZOO digital thermometer has been a great addition to my reef tank setup. The display is bright and easy to read from several feet away, even in low light. It updates quickly and consistently matches my other temperature probes within a tenth of a degree, so I trust the accuracy. Installation is simple — just attach the sensor to the inside of the tank and mount the display on the outside glass. The cable length is generous, and it’s neat enough to keep your setup looking clean. Pro tip: mount the probe away from heaters or return lines for the most stable readings. For the price, it’s an excellent piece of gear — reliable, accurate, and perfect for both freshwater and saltwater aquariums.

Thermometer works very well. You just secure it to the side of the glass and it’ll display temp readings after you press the button. It’s a “set it and forget it” type deal. Very simple to use I did have it paired with a different brand of thermometer in the same tank and they both gave similar readings, so it’s likely very accurate and reliable

Reads accurately. Cheaper than other options and works just the same.

I used one of those cheap stick-on strip thermometers on my 20-gallon tank for about a year. It worked okay, but after upgrading to a 40-gallon and seeing one of these digital touch thermometers on a coworker’s shrimp tank, I decided to give it a try—especially since it was only about $10. ✅ What I Like: Way more accurate than the strip ones. With this, I actually trust the temperature readings—super important when you're dealing with sensitive fish or shrimp. Easy to read and use: The touch display is quick to check with just a tap. I find myself absentmindedly touching it every time I walk by—it’s oddly satisfying. Good adhesion so far: It’s stuck on well for a few months now. It did fall off once, but I’m 99% sure that was my cat’s fault. There were some suspicious paw smudges and cat hair around the area… Clean design: It doesn’t clutter the look of the tank and is simple to install. ⚠️ Minor Notes: The adhesive pad is decent but not industrial-strength. If you have curious pets (like mine), maybe keep it higher on the tank out of reach or reinforce with a backup adhesive if needed. Doesn’t have advanced features: Just a basic thermometer—but honestly, that’s all I wanted. 💡 Final Thoughts: If you’re still using the stick-on strip thermometers, this is a big step up for just a few more dollars. It’s simple, accurate, and looks nice on the tank. Definitely worth picking up—especially for larger tanks where stable temperature is even more important.

We needed an external thermometer for our aquatic turtle 🐢 tank because: 1. I personally don't like a lot of things inside the tank for her to mess with. 2. Her 6 year old human needed something to easily read & something she could check often without disturbing 'Shelly'. This passed both of our requirements. After having had it for about a month, I can confidently say it's very sturdy & easy to read. The temperature is a little off from when I have checked it against an internal thermometer. But it's never been more than one degree. When it dies (because at some point all small self contained gadgets do), Will most likely just reorder this product if it's available.

Looks cool and work great. Bought so it can help me do water changes so I can match the water that was in there previously.
