Hi Wayne and all, There is one difference between my conductivity measurements and the PWT.
As I understand it a PWT measures microSeimens, and I measure microSeimens per cubic centimeter, as my probe is a 1 x 1 x1 cm cell. "Ole Bob" P.S. for Chuck, I don't know if its Siemens or Seimens, and don't give a tinkers dam as to me they are still mhos!!!!!
