Re: Electrical noise (was Re: a note about the hanna TDS meters)

Hello Bill,

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
effects. 

Best,

George
