I have a home made bator out of an ice chest(thanks to many designs found here on BYC) the problem I am having is the meter I have reads 97-99 when the light goes off and 91-93 when it comes on,the regular mercury thermometer reads 85-90 when the light comes on and 100-103 when it goes off.
my ? is : which one do I set my temp on digital or merc?
