Help with thermometers!

[PoultryGirly]

Hi. I just put 14 eggs in my still-air Hovabator yesterday, and I don't know which of my thermometers to trust. I have a probe thermometer that is Exo Terra brand, a digital thermometer/ hydrometer which is Accurite brand, and I have the thermometer that came with the bator. They all read differently. Please help! This is my first hatch and I'm worried!

Place once one in a bowl with cruched ice and water. Let stand for 5 mins. Should be right at 32. I have an accurite dead on. When I buy one i look to find a few that reads the same. And get one of those.

Heres something that might help: http://cmfarm.us/ThermometerCalibration.html

I did the ice thing, and it was 2.2 degrees warmer.in the bator though, that same thermometer says 99.0 and I would have to subtract 2.2 from it and that doesn't make sense. The other thermometer says 100-103 (came with bator), and the last one says 99/100.

did you check all three??

I couldn't check the others because one is digital with no probe and the other only goes down to 70.
