I use good old fashioned glass thermometers when the suckers loose grip you can get a bit of extra use out of them by soaking the sucker in boiling water it makes them supple again, I also like the hang on glass thermo they don't drop off are really slim and look tidy

agree with everyone else, digitals suck, I use a $4 glass one with magnets, no suction cups. Magnet on thermometer inside tank,and a round plastic covered magnet to sick on the outside. Only prob is when cleaning the glass , sometimes I knock it and thermometer falls to bottom of tank, but easily just take the outside magnet and catch the thermometer and run it up the glass back to position. Got them at aq store. hth

That sounds like what I need. Hopefully I can find them in Australia.
If they are $4 there they will be $20 here haha

I also tried the digital ones ended up with two for each of my 2 tanks and they all gave different readings !
Gave up with them
I have a mercury one from where I used to work but am a bit wary of using it in case i break it
I mainly use the digital one on my tds meter its 2 degrees out according to the mercury one so compensate by setting heating two degrees higher

The problem I have is that the tank temps change with the weather but the digital thermometers don't always adjust accordingly so I really had no idea what temps my tanks were

.....and the results are in.

Although hardly an exhaustive test i tried out a number of conventional (ie. non-digital) thermometers from ebay. I checked accuracy at a variety of temperatures and they ranged from 1 degree celcius out to 2.6 degrees out.
Of course it was the last one that i recieved that proved to be the most accurate, out by only 0.2 degrees which i am more than happy with
Hopefully it wasn't just a case of being lucky and getting one good one out of a batch so i have ordered a couple more of these which, all being well, will be what i shall use in all my tanks.
Here's the link for anyone who may be interested.
Dirt cheap as well ;)

i was told the Sera thermometers are best
i also find the digital one i have is out compared to the suction cap style ones
stick on thermometers are a waste of time on my tank, as it has 10mm sides

Stick on thermometers don't last more than a few months and are jolly hard to scrape off the glass too.

My thermometer temperatures are all over the place again and I want to get it sorted
It's unbelievable how useless the 6 different types I have tried are.
You would think it would be easy these days to find an accurate thermometer!

Has anyone used TDS & temp testers in one? I have a TDS tester that seems accurate but how can you tell? I was thinking of buying an accurate one from a scientific instrument company or similar. Has anyone tried that?
Thanks

I just ordered one of these. FINALLY I will know the real temperatures of my tanks and hopefully assist my fish in breeding. A good investment.
I will advise my temps too once I test it
