Review: Very accurate - Read up on lots of different temperature readers and not many were saying very accurate. Bought a new fluval 240 tank so thought let's try fluval! Fitted the sensor at the bottom on the opposite side to the heater as I guess I need the temp at the bottom of the tank for a true reading. The new tank had been heating up for a day so I thought I'd check the water with a cooking probe as I knew that was accurate. It read 24.4°. I looked around at the Fluval thermometer and it read.... 24.4°! So yes... very happy with this purchase! Looks good, nice and compact. Only negative is that you can't read the lcd from side on, only face on. But no issue.
Review: Aquarium thermometer - Look ok but not very accurate

## Questions & Answers

**Q: How can it claim to measure water temp inside an aquarium without touching the water? Seems utterly useless.**
A: The back of these thermometers is black so it absorbs the infra red radiation from the water through the glass into the sensor of the thermometer. I have got one of these thermometers but I don't find them very accurate. Particularly the air temperature reading part. This reading is greatly influenced by the warm water in the aquarium. I prefer the cheaper thermometers that go in the water.

**Q: Should it go more to the top or bottom of the glass please? Thanks x**
A: I doesn't matter were it goes but I won't get it as when I had one it didn't hold its temperature after couple of weeks

**Q: How does it work does some part go into the tank**
A: It sticks on to the side of the tank.
There is a sensore on it and it is fairly accurate,I have one on each of my tanks.

**Q: Does this thermometer have a alarm to alert when the temperature goes above a certain temperature or below a certain temperature? any ideas which do?**
A: This unit does not have an alarm alert - Hagen does not have a model with an alarm I am afraid.Kind regards. Anguel Iordanov

### ⭐⭐⭐⭐⭐ Aquarium thermometer

Look ok but not very accurate

### ⭐⭐⭐⭐ Good but no battery
*by R***B on 22 November 2025*

I found the temperature both for water and room to be accurate but and was very disappointed to find that the product does not come with a battery. No mention of this anywhere. Otherwise would be 5 stars as I find it does its job very well.
