I'm trying to keep the most accurate thermometer right at 100 but it Keeps fluctuating anytime I touch it to try to make it 100 and making me nervous. Is it ok if that one goes down to 97-99, and then sometimes goes up to 101 ? The other thermometer I have in there with it is the one you used and it's always about two numbers behind.
I would go with the one I used..and keep it around 99 or 100.
