Q: about various types of EGT probes.

[Ron Schroeder]

Hi Mike,

Reading a EGT thermocouple isn't a big deal these days.  Many DVMs have a
thermocouple input.  Some even have MAX/MIN functions that are helpfull.
You can extend thermocouples with copper vut make sure the connections to
both + and - are similar so their thermocouple effects cancel.  Using
copper will only degrade the accuracy a few degrees which is good enough
for exhaust work most of the time.
