Does anyone know, can the two types be used interchangeably with a given
monitor, or are they monitor specific?
Type J puts out about 55 uV per degree C. Type K puts out about 40 uV per degree C. If you put a type K on a type J gauge, the gauge would read lower than it should. The opposite is true for the swap the other way.
As I said earlier, type K has a very curvy response and type J has a pretty steady response. Thus, the two types don't interchange, even with a scaling factor. Also, the reference junction compensation would be way off as well. This would put an offset into the reading.
The gauge would tell you "hotter" and "colder" but not much else.
