LED Aquarium Thermometer

About a degree difference from submerged glass thermometer. But close enough to manage the water temperature in the aquarium. I like it because I have one less cable hanging out of the tank, it’s digital, and easy to read. i’ve had one on a 60 gallon tank and another one on a 10 gallon tank for over a year. No problems.

Always been satisfied with this but haven't been completely sure of the accuracy until I got an inkbird water temperature controller. Very happy to say that this thermometer matches the inkbird exactly. Keep in mind however, that this is still a thermometer that sticks to the outside of the tank so it will take a few extra minutes to adjust to temperature, whereas the probe of other thermometers will be more instant. Very accurate, and the battery lasts a long time since the screen is off when not viewing the temperature. Other battery operated thermometers I have had have run out of battery three times over while this one still hasn't.

Only been using for a short time now, but seems to be working great! Quick read time, and once it's on the tank for more than 3 minutes, that part is much less important not sure how long the included battery will last, as it was powered on and running upon delivery. (I can tell you that the delivery van was not well heated lol) The adhesive doesn't seem like it will damage the tank at all, but I'm not sure how well it will be reusable once I peal it off to change the battery. It's about the perfect size tho and looks better than I thought it would attached to the tank. Overall I'm satisfied so far (longevity will be the key here)

Easy install And seems to be giving proper temperature readings. Has been working with no issues for about a month nowIt's fits right on the outside of the tank and is not terribly noticeable.

Works great

This digital "stick-on" thermometer is intelligently designed, easy to place on outside of tank and there's an option for either Fahrenheit or Celsius readings, that is changeable on the back of the unit. These gauges conserve battery by only giving you a read when you touch the front surface, then shuts off, minimizing battery use and frequency of battery replacements. It's also reasonably priced. I've put them on all of my aquariums.

I like this thermometer a lot, wish it stayed lit up all the time but at least it going off extends the battery life. The thermometer is pretty accurate, I also like that it’s small and discreet so it’s not an eye sore on the tank, easy to read, use, and set up.

Works wonderful. You CANNOT replace it once it is stuck on. I couldn’t even get to off at all. It is great if you will never upgrade your tank but it is pretty permanent. I never had to replace the battery over about a year and then we stopped using it since we got a new tank. I got grey and it was fine.

Sencillo de instalar, lo único que no me gusta es que no se queda prendido, tú le tienes que estar aplanando al botón cada que quieres revisar la temperatura

Works great. Satisfied.
