Digital thermometer

[Rogerh]

Does anybody have any tips regarding a digital thermometer?

I`m looking for the kind that only has the probe in the aquarium, I`m not a big fan of having the the ones with a suction cup inside the tank since I like a clean look on my tank.
The ones I have found so far here in Norway, are not showing the correct temp, often +/- 2`celsius.

So what kind do YOU use, and what are your experience with that one?

I was using this one before placing in my Apex, works great.

It seems like quite a bit of inaccuracy between the digitals, even 2 of the same. I found the Pinpoint Wireless Thermometer to be the most accurate, but I always rely on a lab grade glass mercury thermometer as a check against the digitals. The digitals seem to lose accuracy with age, and as the batteries get weak.

I rely on the temp probe on my RKL controller now, but still check it against the lab thermometer.

Digi's are garbage, even the most expensive.
mack is right go mercury.

The digis are nice & convenient. The glass/mercury have the accuracy, but aren't convenient to leave in the tank IMO, plus are breakable.

this one is working for me, I've checked it against a floating thermometer fairly often: (unfortunately is no longer on sale)

The Pinpoint Wireless was reading the same as my glass/mercury when new. I'm not using it now, but at the time I was impressed with the accuracy. Never tried the Lifeguard.

I used to get the cheapo digitals, but almost cooked the tank once when it wouldn't read above 78 as it aged, and I kept turning up the heater trying to warm up the water. I've had some that ended up 7 degrees off! I think those $5 ones don't stay accurate as they get older, plus they have no indication if the battery is getting bad.

unfortunately this did happen to me, i have a merc in my sump now and will never rely soley on the digi. i think with temp being such a vital paramater its worth having both.

I totally agree tundra. I probably should keep my mercury in the sump, but am afraid I'll break it.
