Both meters measure conductivity and particles aren't conductive.
You have it backwards.
Meters detect ONLY ionic content.
The PWT doesn't run the conductivity number through an equation meant for
salt water. Roughly double a TDS number to get what a PWT says.
No meter will measure "PPM", but the numbers are about the same between a
devise that will measure PPM and conductivity readings from a meter that
won't at around 10-12 uS =10-12 PPM.....after the conductivity stops dropping.
The relationship slews off each way in both directions from there a little
bit for a good guess and beyond 30 uS, all bets run off into make a wild guess.

Monette M mentioned that ionic silver 20+ PPM is good to take when one is
ill. How does one measure ionic silver's ppm. I have both PWT and TDS
meters and i understand they measure colloidal silver's particles.
Thanks.
