You can buy any kind of thermocouple wire by the roll, plus excellent technical support at omege www.omega.com. Yes, thermocouples are still used, there is nothing better for certain kinds of temperature work. -- Lawrence Lile John Ferrell Sent by: pic microcontroller discussion list 07/19/2003 09:17 AM Please respond to pic microcontroller discussion list To: PICLIST@MITVMA.MIT.EDU cc: Subject: Re: [OT]:Measuring temperature... 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?
