This sure gives me some encouragement. My three nights this weekend will be 29°F, then 19°, then 9°. That will be a great Incubator test all in one trip! The 9° is a bit concerning, so the pad will come along, condensation or not.
Thanks for the thermometer tip. I bought a similar one at Home Depot years ago and it doesn't even work in my freezer - just gives an error. I'll try this one out.
