## Description

DIGIFLEX Digital Thermometer for Fish Tank - Temperature Thermometer - Aquarium Marine Vivarium – Electronic Thermometer – Tropical Fish Tank Accessories : desertcart.co.uk: Pet Supplies

Review: A little cracker - This is a lovely little item. Battery is easy to replace (someone on a review somewhere said it was difficult but it really is not). The temperature response is not instant, how can it when it has to go through the plastic probe, but within a few seconds it's reading. The probe cable is a nice 36" 90cm in length meaning it can be dipped well into the water and leave plenty spare for keeping the LCD unit clear of water. The F/Celsius switch is also quick and easy to change. I checked the accuracy against three other thermometers and would say it is accurate to with 0.5 of a degree celsius. Perfectly good enough for as an aquarium or water change thermometer.
Review: Good price for device - Nice compact unit, does what it says

## Questions & Answers

**Q: Is this submersible? Do you submerse the wire or not?**
A: You submerse the wire, the dial face has a suction cup on its back so that you fit it on the outside of the tank, it has an off on switch which helps save the battery, otherwise the battery will not last long, I acidentally dropped my first one in the water for a few seconds, that was it, it was ruined, so you must make sure it stays dry. Hope this helps you.

**Q: Does the readout light up?**
A: There is no backlighting or illumination, just the black LCD numerals on the grey background. It's fairly easy to read, however.

**Q: Can i use this in a reptile vivarium, the probe would not be dipped in water as it is a gecko vivarium ? Would it still give an accurate reading?**
A: Not sure, I got mine for my fish tank and it works well with that. I would think it would be fine as your not putting the digital screen part in just the probe.

**Q: Does it matter where abouts in the tank you stick the probe? Would furthest from the heater be best to judge general temperature of the tank?**
A: My understanding is that away from the immediate heated water flow and lower in the tank (warm water rises and all that) is going to give a better reading

Nice compact unit, does what it says

### ⭐⭐⭐⭐ Works reassuringly well; excellent value for money
*by R***G on 3 June 2016*

Having purchased a few useless cheap thermometers for my new aquarium (none of which worked very well), I decided to research the alternatives and found this wonderful internal digital aquarium thermometer. The suction cups on the probe that is inserted into the water allows for it to be secured to the glass, although there have been a few occasions when it has come away from the glass and floated freely (although it still continues to give an accurate temperature reading). The digital display unit itself also has a suction cup, which I use to fasten to the side of the tank, which allows me to see the temperature quickly and be reassured of its accuracy. The unit itself can be turned off easily with the button on the top right hand corner; it only takes a fraction of a second for the internal probe (inside the tank) to display the temperature - and an easy switch allows you to read the temp in fahrenheit or celsius. I also use this little wonder to ensure the water being put into the tank during water changes is as close to the tank temperature as possible so that there's not too much of a shock for the fish. It's accessible, light and manouverable and I highly recommend it. I took a star off for the lack of complete suction on the interior probe, which can be changed using a cheap alternative that can be purchased on Amazon in their hundreds, so at some point I will replace the pad.
