You'd have to be *really* trying to make a thermocouple anywhere near as
slow as that. A fraction of a second time constant is not a problem with a
grounded junction T/C. This can really simplify your control system and
make the tuning of it much less critical if prevention of overshoot of
the actual temperature (not the filament temperature) is a
