Re: Electrical noise (was Re: a note about the hanna TDS meters)
Your largest stumbling block is _polarization_.
In principle, one could use an ohm meter to measure conductivit, though
there would be many errors. Sophisticated conductivity meters have 4
(four) electrodes, just to cancell out polarization and other non-linear
