I can't remember the correct calibration temperatures. Can you please remind me?
Thanks a million,
32F for freezing and 212F for boiling. With Comark’s patented calibration nut, you can easily calibrate your bi-metal thermometer in seconds with only a twist of your fingers. Once it is set, the nut stays tight and firmly in place.

Do u calibrate in hot or cold water and what is the correct calibration temperature?
Hi, the manufacturer's website suggests the following for re-calibration: To re-calibrate, immerse the stem at least 3" into a medium such as hot water of known temperature (212 degrees for boiling water). You will need a second thermometer, either glass or digital, to verify the control temperature.
Wait at least one minute for the thermometer to reach equilibrium. By holding the hex nut securely with a wrench or pliers, the thermometer can be adjusted until the pointer reads the desired temperature.
Turn the nut counter clockwise to lower the temperature. Turn the nut clockwise to raise the temperature.
