Malfunctioning Thermometer?
0
Yesterday I bought a new digital thermometer. The kind that hangs on the outside of the tank, and has a probe that you submerge in the tank.
Well it's reading 73F! This is confusing me, because my regular glass, mercury thermometer is reading 79F. Soooo which one is screwing up?? I mean if I go get a new heater and turn it up so that the digital reads 79, and I kill my fish because the thermometer was screwed up I'll be heart broken.
What's going on??

Is there a dial to calibrate it? Every digital thermometer I've had required calibration.

Hmmm, I'm not sure. I'll have to take a look. About where should it be located?

Mine have always been on the back, or under the battery cover.

Okay, there isn't one that I can see. The only thing under the battery cover is the battery.
Is it possible that the other thermometer is wrong?

Either one of them could be wrong, just because one is fancier than the other doesn't mean it is more accurate. Without a properly calibrated thermometer to test them against, its pretty hard to determine which is correct.
Only other thing I can think of is maybe the thermometers are at different ends/depths of the tank, causing different readings.

That's the thing, they are both in the same general area. I did that on purpose to make sure they would read about the same. Low an behold... Lol.
The digital one isn't what I would call fancy. I was trying to go for something that gave me faster results, and now I'm in this mess!! It was only $10.
I think maybe I'll get a heater that has the actuall temp settings on it. That may help me figure this out.

Figured it out! The display is messed up. It is actually reading 78... lol. For some reason those two line that would make the 8 don't work. Phew!

Ha, what are the odds of that! Glad you got it figured out. Stuff like that can be incredibly frustrating.
