I am trying to build my own thermocoulpe. I was planing to use a multimeter and conect it to a store bought probe.
What sort of probe are you useing. The saleman selling these things had a wide range if probes,ranging from a twisted wire to some rod like ones, some quite pricie. He told me that a propane forge would oxidize the probe and a thin wire one would not last long. Is this true? And how long do you have to have the probe in the heat to get a reading? Do you leave it in all the time or just do spot readings? I was thinking I could make a small hole in the side of the forge and slide it in when needed, and plug the hole when not in use.
Any thoughts on this topic would be helpfull.
Cheers Ron.
