Best Aquarium Thermometer Review

You need to always be assured of the temperature within your aquarium to provide the optimal conditions for your fish to prolong their life. Today we are going to be reviewing the best three aquarium thermometers on the market right now. It is our goal to see if they actually work, whether they are priced fairly, and whether they are going to work the best for you.

Interpet Easy Read Aquarium Thermometer – Best Aquarium Thermometer

The first aquarium thermometer that is up for review today is the Interpet Easy Read Aquarium Thermometer. We really take seriously both the safety and comfort level of your aquatic life. We wouldnever recommend products that are damaging or that are not going to work for your pet.

This is why we have chosen three products that have been built by brands we trust, and that we have never had an issue with. We always recommend looking up reviews and researching the brand itself, as you want to fill your tank with safe devices that will never hinder or damage your fish in any way.

The Interpet Easy Read Aquarium Thermometer is one of the most affordably priced thermometers on the list and on the market right now. This is why we recommend if you are on a budget that you might want to look into buying this one.

The numbers on this thermometer are very easy to read, so you can always know the internal temperature of the tank. At the same time, there is a great temperature band that you can reference that is also very clear. There is both a Celsius reader and Fahrenheit scale so no matter what system you are on, you can use this device.

The Interpet Easy Read Aquarium Thermometer can be fit into your aquarium by a suction cup built onto it. It attaches easily and will never fall off.


  • Easy to use
  • Great suction
  • Easy to read
  • Affordable price


  • Sometimes off by a degree

Doutop Aquarium Thermometer

The next thermometer up for review today is the Doutop Aquarium Thermometer. Doutop is another brand that sets out to make products for the average family—that still work great but are very affordable in price.

With this package, you can either purchase a submersible thermometer or a thermometer that comes with a suction cup; we are reviewing the latter as we feel it is the better all-around product.

The Doutop Aquarium Thermometer is fully digital and comes with both a 1m cable and probe so you can place it in within a tank, an aquarium, a vivarium or a pond. One thing we love about the Doutop Aquarium Thermometer is that it is both concise and compact, so it does not take up that much room.

You can disguise it if you place it next to a filter, so it is never an eyesore and just looks to be a part of it. The reading on this device is also very accurate, give or take 0.1°C, so it is pretty spot on.

One special thing to note is that the Doutop Aquarium Thermometer is not waterproof, which may surprise some people, meaning that you should leave the LCD screen outside of the actual aquarium and just leave the probe in the water. The probe also can work precisely in the air outside of the water, so you can put in vivariums for your lizards or snakes.


  • Easy to use
  • Compact and concise
  • Reading is very accurate


  • Not waterproof, may confuse people

RISEPRO® 2 pack Digital Water Thermometer

The final product that is up for review today is the RISEPRO® 2 pack Digital Water Thermometer. We really do appreciatethe RISEPRO brand, mainly because of their dedication to making products that are easy for the customer to use, and also deliver a lot in terms of durability and productivity!

The RISEPRO® 2 pack Digital Water Thermometer is very affordably priced, and may be a little bit more than the others on this list but the difference is not that significant.

One thing we really enjoyed about this product is that it is very easy to set up. There is a mount display unit that is meant to be put over the tank and it only takes a few minutes to get it all together. You simply mount it on the top, and place the probe inside to start reading the temperature.

This has a very large range and is also very accurate. It has the ability to measure from -58° to 158dFahrenheit, which is -50° to 70° Celsius. It is accurate within plus or minus 1° Celsius, so it is very close to being 100% accurate all the time.

To switch between units of temperature measurement, you can easily do that with just a click of a button.

The RISEPRO® 2 pack Digital Water Thermometer can be used for a lot of different kinds of aquariums or water tanks, and can be used within all types of water including tap water, salt water, marine water, and fresh water, depending on the type of tank and fish you have.

On top of being used for fish, you can use the RISEPRO® 2 pack Digital Water Thermometer for land animals such as reptiles. It can be used in tanks with lizards and turtles.


  • Can be used both on land and water
  • Easy to set up
  • Great units
  • Wide range


  • Wire to thermometer is an eye sore

Final verdict

When purchasing a new thermometer for your aquarium it is crucial that you find one that is going to work the best for you. It really does come down to personal preference as there are a lot of factors including the particular look of your tank, the type of water you use, and so on.

That being said, we think all three of the products above are some of the best aquarium thermometers on the market right now and you should definitely look into purchasing one of them.
