Incubator thermometer question

[Wh00h0069]

I just converted an old freezer into an incubator. I have 2 digital thermometers probes inside, and 1 herpstat pro probe. One of the digital thermometer probes is about an inch from the top. The herpstat probe is about a foot below that. The second digital probe is about two feet below the herpstat probe. The herpstat probe is reading 89F. The two digital probes are reading 87.5F. Which should I go by? I'm guessing the herpstat, because I paid 300 bones for it, and only 5 for each of the digital thermometers. Are these temps going to be fine for incubating ball python eggs? Thanks for your help. Here is a picture of the incubator. (Sorry for the poor quality of the pic.)

you should put a digital thermometer probe in each egg box that you put inside your incubator so that you know the exact temperature that the eggs are being exposed to. thats the only temperature that really matters. all the temps outside the egg box will not affect your eggs.
