I asked you a question, and you answered with a question,
Interesting indeed.
>> Why don't you get a good EC meter and forget all the sales hype
>> and misrepresentation of the facts.
Everyone wants a 19 to 29 dollar meter and expects laboratory grade
results.
That is not the way the cookie crumbles and now the way the world
goes around.
Not really true. Most reasonable people understand pretty quickly
that a meter is just a guide.
As I Have stated before, NO PPM meter exists in the world today.
Period.
That will be news to all the makers of PPM meters.
There is a move within the industry to combine EC and PPM. They
are catering to the unknowing
and the people that want only approximations.
There's no 'move' to combine EC and PPM. There are PPM meters, and
there are EC meters. Some meters have offer both in separate modes
but no-ones trying to 'combine' them.
Just about every measuring instrument gives an 'approximation'. How
accurate is your speedo? Most people can live with this fact.
True instrumentation is somewhat approaching a Science. No
guesswork and no approximations.
Some sensors can cost 500 to 2000 dollars and lab grade
instruments, much more.
I am working with a system now, designed by a chemical engineer,
whereas one sensor, accumulated totals, and other fancy features
cost 15 K. I am not sure the system will fly without a
federal grant. Knowing the FEDS, they may give him the money. The
control system alone will cost about as much as the total system.
He wants this critter fully automated.
Several 3000 gallon input tanks and one 10,000 gallon output tank.
Sensors and instrumentation are a very important part of the world
today.
( Not TWO BIT meters that are labeled wrong )
TWO BIT meters are fine when used in their place and as long as your
expectations aren't unreasonable.
Back to your question, below are two statements that are either
half truths or
outright LIES, depending on how you view them. ( Many others
similar exist )
I copied these from some TWO BIT statements about meters.
As the author of the 'TWO BIT' statements you refer to perhaps I
should be offended but I can barely be bothered to respond.
TDS or PPM meters measure the electrical conductivity of the water
and, using a built in program convert that to an approximate PPM
using known conductivity>ppm values. They are pretty reliable in the
ranges they are designed for and when measuring what they designed to
measure (Basically thats dissolved salt). Using a TDS or PPM meter
to measure CS (way down at the bottom of the range) is pushing things
to extremes but nevertheless I've found they are extremely handy and
surprisingly consistent.
To say, as you do, that 'no PPM meter exists in the world today' is a
bit like saying no 'Laser Measuring Device' actually exists.
Technically thats true because laser beams doesn't actually 'measure'
anything but by adding a little step to the equation (like knowing
the speed of light) then they do a pretty good job and, I think,
satisfy the Fair Trading authorities, and NASA.
One other thing that may be confusing you Wayne. PPM isn't an
indication of the number of particles anyway. Its an alternative way
of saying 'milligrams per litre'.
The statements below are certainly not 'half truths' or 'lies'. In
fact they were very carefully worded to provide maximum clarity for
the reader. Perhaps that something you should consider in your own
ramblings.

David
Again, NO PPM meter exists today, even if it is calibrated in PPM.
==============
1. You can MEASURE the ppm of the ions in your silver water with a
TDS
or EC Meter,
2. A TDS (Total Dissolved Solids) meter is an extremely handy
addition to your colloidal silver kit. It measures the initial
purity of commercial or home distilled water, and provides a useful
guide to the final ionic PPM (Parts Per Million) of your colloidal
silver. Its also very handy for testing the quality of your mains
water, rain water or bore water.======================
My idea only........... Pure Water Tester ? Why test Pure
Water ? Seems bogus to me.
I worked in the 90 deg heat all day yesterday. I guess it warped
my mind.
