Re: CS>TDS meter

[Ode Coyote]

Can't be done with a meter.

 To quote Frank Key, "You are spinning your wheels"
You can 'guess' at it, factor in some vague variables and find the
ballparks parking lot.
To find home base you listen for the cheering crowd and you still don't
know which team is up at bat till you get there.

Even a half million dollar AA Spectrophotometer averages 3 runs of a sample
and may STILL be way off.

 Nice part is, you get to use an 'X'  megaton nuke to vaporize the entire
ballpark and the whole section of the city it's in, all without hurting the
crowd or the teams, without leaving a cater, or even scorching any cars or
the grass on the infield.
 How many megatons is irrelevant.
 If one didn't do it, use 20 or 50...the difference only being how much
water went with it. [and the water, itself, is more dangerous than the
silver that's in it ]

Re: CS>TDS meter

[Ode Coyote]

I have abandoned using meters as a measure of anything over around 10 uS
and gone to using the Faraday equation as a predictor.
 With 1 milliamp on the electrodes, [achieved at around 6 uS] running a
quart sized batch...just figure 2 PPM per hour after conductivity related
auto shutdown.

Even this is an averaging of meter reading uS over time plots which run
pretty much linear up to 30 uS and then start to slew low as
supersaturation triggers significant realtime unreadable silver content
formation...and Faraday equation prediction which only says how much silver
leaves the electrodes, but not what happens to it afterwards.

The "Silver 7"  [with switches on top] was set to shut down at 20
uS...according to a meter...with the vagaries of meters and electronic
components at +/- 1% accuracy stacking up and including  temperature
variations affecting both readings *and* readable silver content...so may
be 15 to 18 uS [but 'who knows' how much actual PPM total silver ]

But also based upon AA Spectrophotometer readings by Frank Keys Colloidal
Science Laboratory where there was a very close match between my reading of
12 uS to his results of 12 PPM total silver. [within a decimal]

Other labs [such as the NC State Water Lab which does nothing BUT test
water]  NOT specializing in ionic/colloid mixes specifically of silver,
returned as high as 50 PPM which were WAY off base.

 It's all about making an "Eddicated Guess" which is maybe 5 steps beyond a
wild guess...and better than trying to count how many Sasquatch there are
in a nature preserve by listening to tree knocking.

With the  'real world' [sometimes called reality] where too much is highly
unlikely to be a problem and no one ever  knows how much is too little
until it doesn't do the job...and absorption/delivery to any given place is
a total unknowable in any given situation... an eddicated guess with a
random multiplier gets the job done.
...and overkill?  It doesn't take a backhoe to clean up.
If a garden hose will wash the driveway clean, no problem using a pressure
washer either.It's only just [silver] water and the  [Multi-celled
organism] fence next to the driveway is safe.

You flush the grime down the drain till the water runs clear...right?
