Dude, I "teach" engineers about instrumentation and measurement. I design instrumentation for a living (and have done that the mentioned forty year period).

Dude, I am confused. First you say your expertise is analytical chemistry, now you are saying your expertise is electrical engineering?

"Dude, I am confused. First you say your expertise is analytical chemistry, now you are saying your expertise is electrical engineering?"

Again....you think only electrical engineers can design instrumentation?? All my customers must be imagining the devices they have bought and used over the years.

But I see you still want to play the "thousand one-liner replies" game. Not gonna do that. Don't have either the time or the interest. Bye. Permanently.
