its a hovabator 1602n.
I have the probe set up outside the egg box becuase i read that it was best to take the temps of the bator that way you know the egg box is right on. I kinda think that if the temp in the bator fluxuates a little that it is going to take time for the egg box to upper or lower its temp to match and by the time the egg box would have a chance to flux much the bators temp is correcting itself already.
if that made any sence.
