      Jeshua:Like I said I will read the info about how to make a thermocouple. If it looks like it will work I will give it a try. Just because I get a reading it may not be accurate. I still need a meter and special wire to hook it up. Then their are many different types of thermocouples (K, etc). Which type might a simple piece of platinum wire correspond to? Thanks Carl

Still I am a little skeptical that they are able to charge over $400 for something that could be easily made for $20. With competition somebody else could make a good profit at $200.

      I would just order some platinum wire, hook it up to your termocouple and see what happens when you put on torch on it.

      Thats a five minute $1.75 (plus S&H) experiment.
