- I can only offer anecdotal experiences, since I live on an island with the ocean on one side (about 330' from the house ( NNW to S) and a saltwater bay about 350' on the other ( N to SSE). I often ca

- ACtually, water conductivity measurements are made with AC (to avoid polarization effects). 60 Hz or 1kHz would be common frequencies. I doubt that the conductivity is that frequency dependent, altho

- Depends on what you mean by simple, and what sort of spatial resolution you want. A straightforward 2 or 4 probe resistance measurement at 60Hz will get you in the ballpark (within a factor of 10, an

- One's the inverse of the other.. Siemens == mhos Conductivity is in Siemens/meter (S/m) (or, more commonly for water, microsiemens/cm) Resistivity is in ohm meters (or, more commonly for water Megohm
