Hi to all experts in labs and others that can provide comments:
I know that PPM measurement is an important
item to all people producing CS.
FYI - I have a BioGuard Multi-test 1200V (model name)
that I used to check the water in my swimming pool.
This kit performs 5 important pool and Spa tests.
One of these tests is PPM reading. I paid a few
years ago $30.00 Cdn for the kit. The kit comes
with 5 different liquid (reagent) to perform the
various tests.
If I understand correctly, PPM is a measure of
parts per million in a liquid. (I presume referring
to some sort of metal or material in that liquid).
I have used this kit to measure PPM in the CS that
I have produced and according to the reading, my
CS would read between 10 - 20 PPM.
The accuracy of the result is +/- 10, due to one drop
of a specific liquid used to test the water represents 10PPM.
It is not very accurate, But I wonder if this would represent
a better picture of PPM in the CS than the TDS-1.
My TDS-1 reads 5 on the digital readout while this
swimming tool kit would read between 10 - 20 PPM.
My CS is produced using a 30Vdc power supply with
0 ppm distilled water (heated water to speed up the process)
and using continous stirring. No current limiting used on this
batch and the producing time was for 2hrs.
What I would like to know from the experienced people dealing
with PPM what comments they could provide about using this crude
test to measure PPM. I know that again it reads a total, but
if you start with pure nickel and pure distilled water and insert
only silver in the water, the final result must be majority
silver...
I understand very well that the best measurement is from
a lab. However, it is not practical for many people to carry out
and if this could give them an approximate reading, perhaps that
it may help some of us.
I would like your recommendation as far as this kit is concerned.
We know enough about TDS-1 now, we should comment only
on this kit if possible to avoid confusion.
I want to thank the people in advance that will take the time to
provide useful comments.
Gaston
