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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by on Reviewed in the United Kingdom 10 July 2026* Work well ### ⭐⭐⭐⭐⭐ Very accurate *by on Reviewed in the United Kingdom 2 June 2024* 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. ### ⭐⭐⭐⭐ Good thermometer for water temperature but the room temperature is inaccurate *by on Reviewed in the United Kingdom 2 May 2024* 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! ## Frequently Bought Together - FLUVAL FL wireless 2-in-1 Digital Thermometer - Fluval Aquarium Air Pump - Fluval T300 Fully Electronic Heater for Freshwater Aquariums up to 80 Gal. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/48157720-fl-wireless-2-in-1-digital-thermometer](https://www.desertcart.be/products/48157720-fl-wireless-2-in-1-digital-thermometer) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-22*
