Thanks Ode this is already over my head. Is there really any reason then to get one of these meters? Would it just be better for me to use manual swap after the auto swap shuts off on my silverpuppy? PT

The problem with using meters on solutions with limited solubility. [ESPECIALLY "PPM" meters set up to measure salt water which is very highly soluble] The ionic portion of CS has very limited solubility and some portion will convert into an un-measureable colloid depending on variable environmental conditions. The Silver is still in the water, but a meter won't detect it. The instant power is off, conductivity starts dropping. The stronger you made the solution, the more it will drop...by around 40% Each time you bump it back up, it will drop by about 1/2 as much as the previous time, but anything over 30 uS will drop back to 30 uS over time.
