Just in case you are curious how to calibrate your thermometers it's pretty simple. You make a slurry of ice water. This simulates freezing temperature, which is 32F. If you swirl it around for about a minute with your thermometer tip in it, it should read 32F. If it doesn't, some thermometers you can manually set it to read 32F and some you can't.
