Don't overlook medical thermometers for the area around 100 degrees F. Also, back in the dark ages we used thermocouple wire, a reference junction in an ice water bath and read it with a balanced bridge (no current draw!) I am inclined to believe that a good DVM and a piece of Chromel-Alumel or Iron -constantan wire could be used for your purposes. I have no clue as to where to find the wire today.

Any of you folks have a way to measure temperature semi-accurately w/o expensive thermometers? Within a few degrees would be nice, and in the range of 0 to 300 deg F. I'm trying to test the calibration of a temp sensor for my car. I can use ice and hot water to get the 32- and 212-deg F points. But is there a way to get 1 or 2 points between that, and a couple other points up to about 300 deg F? Is there any other liquid I could boil that has some known boiling point perhaps?
