" uS" is units of conductivity in Microsiemens per cubic centimeter as
read by an "EC" meter [electrical conductivity ]
That number just so happens to correspond very close to PPM up to around 30
uS...after..it has stopped dropping over time.
Silver water loses some conductivity as it stabilizes.
It's not actually measuring "PPM" silver, but hands you a useful number.
A PPM/TDS meter works the same way, but fudges the conductivity number to
correspond to PPM of Sodium Chloride salt in salt water....*about* 1/2 the
conductivity number...so, when using a PPM meter, double the reading.

How do you measure concentrations of silver and what is uS (units Silver?)
