Conductivity [uS] is conductivity, so 442, NaCl and KCl is irrelevant.
The uS conductivity number closely corresponds to the PPM number ..after
the conductivity stops dropping...up to around 30 uS....as derived by $$
Atomic Absorption Spectrophotometer tests $$ done on samples averaging 12
PPM @ 87% ionic as the middle of a range.
Little or no Tyndall Effect, [as seen in a laser beam] fudge the number
down some...heavy dense TE fudge it up some, to compensate for the
unreadable particulates.
Beyond 30 uS water solubility limits create conditions where conductivity
measuring is **pretty** much useless but can still offer some hints when
taken before it drops.
Using constant current means a linear ion emission rate, so plotting
conductivity rise over time at a given current, you can extend that line
past 30 uS where it starts going non linear with unreadable particle
formation and predict PPM as uS that can't be read.
But a second uS drop back chart would make that a lot more accurate and
that's probably not linear and would take many time stabilized batches to
compile.
Some say that Faraday Equations correspond with conductivity measurements,
but Faraday doesn't account for waste products...ie "where" the silver is.
Obviously, not all of it stays in the water. [Yet another chart to
average in? ]
BUT
In the REAL world where application is pure common sense intuition and no
dosing recommendations make any sense at all because every person and every
application is unique, "ballpark" is good enough.
It's nearly impossible to over do and the major difference is just water.
A particle too big to get out, never gets in and the sizes range all over
the place in any given batch. Your body has a great and intelligent
filtration system if IT is working properly...and if it isn't, you'll
likely be having some other much more serious problems than turning blue.
A Claymore mine and a sniper rifle do the same job when the scenery doesn't
care.
Do what works and if it doesn't, do it different till it does..and if it
STILL doesn't, do something else as well. [Like, toss in some DMSO and eat
a lot of carrots]
When you forget that you need to, you are done. [Until something reminds
you, if it does ]

Just unpacked my brand spanking new COM-100. Many cool features that I
know nothing about. It's neat that the instructions actually mention CS.
Can someone give me the short lesson?
I'm thinking I want the mode at µS and 442. This is different than the ppm
that is talked about. Is there any conversions I have to do for say a 10
ppm solution? Please help me understand.
Thank you,
Jeff

HM Digital makes a decent PPM meter [TDS3] ..but a PPM meter isn't what
you want...they are designed to meter "salt water" and silver water isn't
salt water.
Looks like this one is on the low end of their line.
A PPM meter is useful for CS ...but not very.
Try an HM Digital EC3
