Dear Wayne:

many people use the EC meter and call the results ppm metes does not a
ppm meter exist.
Actually there are at least two scientific instruments that directly
measure silver concentration. One is a probe similar to a pH probe that
specifically measures silver concentration. The other is a photo
spectrometer. Neither one is cheap. I have been to Frank Key's lab
several times and the device he uses burns the silver sample in a plasma
then measures the frequency spectrum emitted and the magnatude in relation
to a certified standard.
Interesting indeed.
I made the statement that some high priced instruments exist that will
measure a single salt.
Possibly these fancy devices would be covered by that.
I am not the only person that says this about ppm meters, many others have
said the same thing.
It just so happens that the collidal silver made by my generator shows
that uS is a 1 to 1 realation to PPM using the Hanna PWT tester. Other EC
meters probably will be different. See the test report at
How did you manage that ? Looks like that would depend on the water as
much as the CS.

Maybe I should have said, no Standard ppm meter
or...... No off the shelf ppm meter, that one could afford and use exists.
The EC meters that are showing ppm have internal calculations much like the
people on the list are using.
Back to your original statement,
>> Actually there are at least two scientific instruments that directly

I am fully aware that any machine, device or instrument can be designed and
built to
accomplish virtually any purpose or virtually any task.
And, ........ I have no doubt that every think you say is 100 % correct.
My only slight difference and problem is that one would consider these
highly sophisticated instruments, costing many thousands of dollars to be a
ppm meter.
They appear to be a single purpose instrument.
I don't think you even said that they were ppm meters. <grin>
It disturbs me that the instrument industry is talking about combining EC
and ppm
and having only one unit. Not sure what they could call it.
I believe that many would never accept it. ppm is an absolute. EC is also,
but they are not the same thing, and never will be. In rare cases, pure
water and one item, and they will be close, as you stated.
