Can the battery be replaced?
Answer by ChewyJan 02, 2019
The thermometer includes LR44 batteries, which can be replaced.

Will this work with a aquatic turtle? Thank you...
Answer by ChewyMar 09, 2018
This product is intended to read the water temperature in all aquariums, including those for turtles.

Could you please tell me the highest temperature range this thermometer will register. Thank you!
Answer by ChewyJan 18, 2018
From Customer reviews it has been tested from 120 Fahrenheit to -7 Celsius. The average temperature you'd use it at is 76- 84 degrees.

can i use it to test on several tanks?
Answer by ChewySep 07, 2018
This thermometer can be used on several aquariums but should be cleaned thoroughly before entering the next aquarium to reduce the risk of spreading any illnesses that your fish may have.

Inaccurate but consistent

I've had this for 8 months now. It is consistently about 2.2 degrees F above the actual temperature according to two other thermometers that I have. Knowing that, it works for its purpose. The suction cup gave out completely after the first hour of use and has never worked since. I'd recommend this for ease of use but you'll need another thermometer for accuracy.

Helps me with the water

So i had my heater set on 86 in the water and it with light on it read it to be around 92/94 - With the light off it read to 91= SO this helps me gauge where the heater needs to be so I would not harm my pet.

Good Thermometer

I use these thermometers in my aquariums and when I'm changing the water in my tanks. The batteries last a long time and you can get readings in Centigrade and Fahrenheit.

Junk, Junk, Junk!!!!!!

There is no other word to describe this product. Junk, a complete waste of money! I have used for several months now. It has never given an accurate temperature but was only off by a few degrees so I wasn’t completely worried about it. But today while cleaning my tank, I went to log the temp and it’s reading in the negatives. I highly doubt my fish would be thriving in such cold water. So this product literally lasted 6 months and now has to be part of our ever growing landfills. Thanks China!

Worked For A While

This worked for a while, but is now reading 5 degrees low. I've changed the battery and still the same issue. Look elsewhere.

Broken right out of the box

Can't review something that was completely broken right out of the box. The thermometer would not turn on after trying both the battery that came with it and a brand new battery. DO NOT waste your money on this

Bad thermometer

The thermometer did not work right out of the box. Checked battery it was fine but you could only see a broken read out.

Started out good, then lost accuracy

I was very happy with this thermometer. I tested it a few times in comparison to my food thermometer and it was spot on! However, after about 2 weeks it started telling me my water temp was only 72 degrees, which had me concerned that my heater went out. So I tested it against my food thermometer again and the food thermometer had a reading of 77, which is what I had my heater set to. So the heater was apparently still functioning fine, it was the thermometer that stopped giving accurate readings. I've left it in my tank for the past month and it's never given a reading over 72 degrees and I've tested several more times and verified that my water is still at 77 degrees. It's possible that it already needs a new battery, but I'm still giving less stars because even if that is the case, I shouldn't have to replace the batteries that often.

Accurate Thermometer

The thermometer accuracy is pretty good and show a constant reading every few seconds or so. Mine came with a battery and two suction cups. One for the thermometer to hang onto the glass and one for the probe. Suctions work well so I’m not disappointed. The only problem I have is that if your night at eye level with it you can’t see what the reading are.
