Double wafer thermostat system for my Monstabator?

[TedJan92_in_Idaho]

Using double wafer thermostats. If I set one to turn off at lets say 99.7 and the other to turn on at 99. 3 what kind of accuracy can I expect out of this?? I'm in the process of building my Monstabator that will hold around 750 eggs. I am open to other options as well. Just looking for the most accurate system.

Running two wafers wont make for a more accurate thermostat than just one. When one kicks off the power is off till it comes back on no matter if you have a second one or not. Using a second thermostat is about safety/backup. The second is set at around 101. If the first thermostat fails in the on position the second one will start cycling when the incubator gets to 101 saving the eggs from being cooked. That is assuming the second thermostat does not fail before the first one. Odds are that it wont but it can.

Here's my thoughts on picking a thermostat.
