I have checked them all to 2 lab thermometers. Matching up with beersmith also makes me feel that thier pretty close. Also before I did mashouts my fg would come in lower than the calculators.Denny, with your contacts at SN do they do a mashout of any type? May just be a difference in process.
IIRC, I think they do. But I doubt that explains things. I can ask them, but it will be a while since we're into Thanksgiving now.
How do you know your thermometers are accurate?
