I do know that my readings for humidity are different at the bottom of my Genesis than what the digital readout says. So, I always go by what it says on the level the eggs are, and it is always higher there, by about 10%. However, you should not be seeing that much of a temp difference. To be honest 2 hrs of running is not that long, do you have the vent plugs open? I would open the vents, and just leave it over night and see what it reads in the morning.
I don't wear gloves to candle but I do wash my hands with antibacterial soap just before I do anything with them. I don't actually take them out of the turner to candle unless I need to get a better look at one, I have a small flashlight style candler so I just light the egg from the top down and usually that is enough to see if there is development and if there is still life there or not...this way I can candle without actually handling the eggs. Of course the lights are off in the room to start with which helps, and I only candle at night so I don't have to worry about daylight coming in.
