If it's a dial thermometer you can calibrate it...on the back where the stem meets the back of the dial you should find a nut...turning the nut moves the pointer on the thermometer.
Put it in boiling water and turn the nut till it reads 212° (wear protective gloves or be VERY careful...steam burns are PAINFUL)...
Confirm the calibration by sticking the probe in a glass of ice water... should read 32° .
I'd check both for accuracy using this technique before tossing either.
I check ALL my thermos this way...even brand new digitals, and re check them every few months.
