I have been using coralife dig thermometer on all my tanks for awhile always thought that was sufficient. On my 240g i had a fish health problem and i needed to bump up the temp read 83.7f and it would fluctuate a little i adjusted heat but i couldn't get the temp where i wanted it .So i put another thermometer on the other side of the tank ,it being 8f long i got 75f so i thought my heater on that side must be broken, to make a long story short i took another thermometer and it read 75f so one is reading high, my black aro is dead i thought i had raised the temp to treat her and my tank was cold. so needles to say i have lost faith in my thermometer and i need very precise readings can anyone recommend something.

I use a digital from VWR Scientific. This device has a probe which goes in the tank and simultaneously gives a readout of both tank and ambient temperatures. The contrast between the two temps provides reassurance that you are getting an accurate tank reading. The large LCD readout is easy to read. It's never failed in 3 years.
i use a ranco temp controller, but have had it only a few months so i cant say about its longevity. http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=13967
i do agree those cheap 6$ thermometers suck, i can put 3 diff. ones exactly in the same spot of the tank and get 3 diff readings, some ranging 4-5f difference.

I have a couple of hannah electronic testers. All have temp on them so I can check the temp with each one while I check everything else (ph, TDS, ORP, all that good stuff) and see if there's a difference.

Instead of telling you what I use I'll answer your question on how to get very precise readings.
Your best bet is to get a high quality glass mercury or red liquid thermometer. Find one that is used for laboratories. This will give you your most precise reading.
You can then use this precise thermometer to do a baseline check on a cheaper thermometer like a digital.
The digital may be off but they will be consistently off. If your digital reads 80° and the glass says 78° then you know to subtract 2° from whatever your digital reading says.
You can also do this to check the cheaper floating or suction cup glass thermometers as they usually off a little also.
Stick ons? Forget em.

own one accurate liquid in glass thermometer and find the correction factor for you digital or other thermometers............might get a really good one and share with fish friends

Or find a fish friend that has one and just use his!
