Looking for best conductive metal for DC probe for water immersion

I am trying to make a sensor which conducts in water and doesn't corrode or corrodes after couple of years if DC % volts being passed thru it in water. Which metal is suitable for this?

The best material is probably platinum-clad titanium, Zubair, but suppliers of probes have used copper, brass, stainless steel, and a host of other materials. Good luck.
