I had been using my dial thermometer for some time, and noticed that the boiling wort was always at 206F. So I got a couple new ones. The first gave a boiling point reading of 210F, somewhat better than my original, but when I checked the melting point, it came at 37F. The second new one gave a boiling point of 222F! But its melting point was right at 32F. Since I live only a few hundred feet above sea level, I would expect the true boiling point should be 212F and the melting point 32F.
Now, since I do all grain mashing, the rest temperature is very important (I want it to be 150 to 152F). My question is - Can I trust any of the thermometers at this in-between temperature? Or is there some way to calibrate them?
