Best Aquarium Digital Thermometers Reviews
I will now go in to more detail to let you know what I like and what I don’t like about all of the thermometers in this review.
[block]30[/block] Zacro LCD Digital Thermometer Review
This is a great little thermometer which has a nice big easy to read display and comes with two suction cups which help to hold the thermometer in place. I have been using this product in my 60 gallon tank and I can say it reads the water temperature very accurately. I have been using this for five months and have had no issues with it, I highly recommend this product.

Rated #1 Digital Thermometer By HelpUsFish[block]32[/block] Jcreate Aquarium Thermometer Review
This thermometer really surprised me. You stick it on the outside of your tank. It has a backside temperature sensor. I thought this will not measure the water temperature accuracy! Oh how I was wrong, it is very accurate at measuring the temperature. I love the large LED display making it easy for you to read the temperature. Operation:

This is a great little thermometer which has a nice big easy to read display. Again in my tests this measured the temperature of my aquarium water very accurately. Can display the temperature in C or F, you have to remove a jumper at the back of the device to swap. The only thing I do not like about this unit is that you need to connect the USB cable to a PC or power socket.

[block]37[/block] Fluval Celcius Digital Aquarium Thermometer Review
This is by far the cheapest product on my list, currently it is selling for $4.99 on Amazon. It might not have as many features as other thermometers such as only displays the temperature in fahrenheit, Doesn’t have an alarm, Basic looking display. Having said that it does exactly what you want and it does it well. The tests that I did it measured my aquarium water very accurately, Was very easy to setup and use and has currently lasted 5 months with no issues. I highly recommend this product if you are looking not to spend a lot of money.

[block]43[/block] Lifegard Aquatics Digital Temp Alert Review
I for me this is the best product I have reviewed. The only reason why I did not rate this as #1 is because of its price. Currently it is selling for $42.52 on Amazon. This product has a lot more features than the others which include an alarm if the water temperature goes below or above what you set. It also displays two temperatures, the room temperature and the water temperature. It also uses a AAA battery which I like as this is a higher capacity battery compared to the other products. This product also comes with a stand or sticky back which enables you to easily place it on your aquarium tank.

This product has no wires / probe, you attach it directly on to the outside of the glass in your aquarium. It also has an alarm if the water temperature goes below or above what you set. In my tests the water temperature reading were out by 1 fahrenheit, I don’t believe this to be a big issue. It also does not come with any batteries, You will need
