That's great but it seems like the majority of beginners are having
problems with the iron. As they not only can work well but usually
require zero investment, it is still well worth considering a better way
of using them.

True, if there is only one variable, you are home free but this is not
the case as you still have board size and thickness which effect the
surface temperature as a function of time.
Also most people have mentioned that it takes more than one pass and I
have heard of more laminators that don't work or need to be modified
than from people totally happy with them.

How would you measure the transfer medium temperature with a thermocouple?

The best you could do embed it in whatever the board rests on an measure
the temperature of that general area.

With the IR meter you can scan the entire surface in about a second and
know the temperature of the only place that matters.
