- Jan 4, 2012Ernie:I was hoping you has figured out a cheap "do it yourself" solution. I think what I might do is bury one of the cheaper thermocouples under a thin layer of refractory. That should give me a relative reading. Say if iron melts at a 2000 degree reading I will know the next time I need to heat to 2000 degrees again. It would also be useful to see how a change to the burner will change the temperature. Thanks Carl

Yes, you were right it is a 'R' type thermocouple probe and when I purchased it 18 years ago it was insanely expensive and I don't think anything has changed at the present time. It has been really helpful in fine tuning my furnace so I can get hot cast iron. I think the second hand market would be your best bet.
