a quick clip where i test with a TDS (Total Disolved Solids) meter to see if the Silver Solution bought from a chemist for $15NZD.
the bottle states 10PPM
however the reading of 92PPM show that it is not pure DISTILLED water with only 10PPM in it.
This is why i opted to by a distiller, tds meter and rods, now i make my own 20ppm solution far better and stronger.
