I had to design a conductivity sensor controller for
work a few months
ago. Its unit of measure is microsiemens.
We're STILL getting good mileage out of that around the office. =)
Just for the lulz, yesterday I saw a current amplifier that works in the
order of FEMTOamps (!!!) and uses - gasp - 10 GIGAohms resistors :oO Things
I never saw in my life (used in gas chromatographs)
World and life are full of interesting things :D
