Temperature Probe Readings

[levi]

I received my temperature probe today and happily hooked it up to measure the temperature of my turtle tank water. For the first few seconds I got the accurate reading of about 28 C degrees, but shortly after the temperature reading jumped to 39 C degrees and now the temperature is hovering around 39/40 C degrees. The heaters are set to 28 C degrees so it appears the reading is inflated for some reason. Did I make an error in the configuration?

On another note, is there an explanation of what each module setting means?

Does it go back to room temperature if you pull it out of the tank?

Thanks for the troubleshooting suggestion! The temperature normalized after about 10 minutes of sitting in the water. I will try your tip if I see false readings on it again.

Hi Levi... I've been having a similar issue. The temp probe works perfect outside of the tank but not inside (underwater). I've tried multiple temp probes, different channels, different settings and I've now even tried a different IO204. Thinking it may be stray voltage in the water, I purchased a grounding rod. I've tried leaving everything (lights, pumps, etc) off. pH and other water quality tests show the water is ok. All this and it still keeps happening. I cannot lock in on anything as a cause.

Now, I'm exhausted of trying to fix it. So my band-aid to the problem is simple and has been working for months now. I took a piece of aquarium air hose and threaded the temp probe into it. Then sealed the hose and dropped the end into the water. It obviously wont react to fast temp changes, but its still accurate and hasn't messed up since.

Just an option for you. Good luck..
