FLUVAL FL wireless 2-in-1 Digital Thermometer

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.

This thermometer works fine,I have checked the temperature against the one that is inside my tank and they are the same, it now saves me removing the glass internal one for cleaning and then trying to get the suction cup to stick again etc...Very easy to attach via two strips of Velcro and works as soon as the battery is inserted, battery is also included. It can show either deg C or deg F. There are two large easy to read displays, The top display shows tank temp and the lower display shows room temp which helps during hot and cold seasons if you have tanks in a garage etc.I have seen these in stores for £22.99 so are a good price at £13

I have a tropical fish tank and an axolotl tank in the same room.I tested the water temperature of both tanks with a standard thermometer alongside the Fluval one and the water temperature was accurate on both. There was roughly a 5-8 degree difference between water temperature in the tanks.However, there was also a 5-8 degree difference in the room temperature of both tanks (dispite the tanks being in the same room, no more than a few feet apart).So the water temperature is accurate but don't rely on the room temperature. It appears to be influenced by the temperature of the tank it's attached too.So if you have a heater in your tank chances are the room temperature will be inaccurate.Other than that minor issue it's a good product and I will be using them for some time to come!

Standard delivery fee and came the next working today and well packaged so 5 stars for ordering process. Have been looking for compact easy to read LCD thermometer for my marine tank sump. It may looks big looking at the picture on the Amazon website, but the unit is only 4 cm wide and 8 cm high. What's really good about this Fluval 2-in-1 Thermometer there is no unsightly wires or probes hanging in the tank!. One small down side, It takes about 5 to 10 minutes to get a stable temperature reading. Information on the packaging stated accurately is within 1C / 2F. I found the accurately is more like 0.3 C to 0.7 F so that a big plus. I would buy this Fluval 2-in-1 Thermometer for other new fish tanks projects in the future.

Sits on outside glass of fish tank ,two displays one water temp,one room temp unfortunately as it’s so close to the glass both temps are within a degree of each other meaning room temp not correct,your probably better off with a cheap £3 traditional one.

Works well.

I wanted to upgrade my old thermometer with this one and wow it works well and nice and easy to read

I like that the item when stuck to the aquarium is easy to read though I doubt the accuracy of the room temperature it is very accurate on the aquarium temperature. Checked via spirit thermometer.
