Digital thermometer reading 180

So I took the digital thermometer out of my gf's tank and put it in mine to get a reading. Gf's tank is reading 79 degrees but when I put it in my tank it reads 180!

What would cause that?

Does it go back to 79 when in your GF's tank? Stray voltage causing the reading error maybe?

Yes it does go back to 79 in the gf's tank. Tried a different one and it's reading 78 in my tank. Haven't tried it in the gf's tank.

At the time I had brand new heater, my return pump and my skimmer going that's it.

I'll have to check for voltage. Can I just stick two leads from a fluke in the water?
