There is a nut like thing at the base.I carry something like this at work all of the time.
Mine can be calibrated on the spot.
How you calibrate one is to get ice water and stir it up put the thermometer in it.
It should read 32F or 0 C.
Mine has a built in place on the cover you put the thermometer in to hold it.
You twist the dial cover and all till it reads correctly.
These things are cheap and worth every penny.
