Why no more stirrers: Magnetic: Everything is made in China now [ie motors] Quality control has gone out the window and I just can't get motors that will predictably last even after weeding out 40% of them as obviously defective. Even the very expensive custom American made motors were only 80% usable I've redesigned for different motors 8 times now and each time the quality and consistency erodes ....and a stirrer was only needed back when generator output was DC.
But it's more personal than that. It hurts my feelings to sell "junk", especially junk you don't need. No amount of stirring will touch the Nearnst Diffusion layer at the electrode surface where things happen on the "Micro" atomic level. The "Macro" diffusion level is sufficiently handled by natural convection, Brownian Motion and ion velocity. The thermal stirrers heat the water when you don't want the heat. At 20 PPM the solution is in over saturation and ions are more forced into becoming uncharged molecules of silver oxide and hydroxide. Sometimes on a cold day the auto off at 20 uS would predominantly make particles before it reached 20 uS and never shut down. Heating the water helped on that score by raising the saturation point of the water but with every 10 degrees of temperature 3 uS in conductivity is added, so, at 20 uS and 90 deg F water 6 uS was from heat, not silver. Hot water makes ions more chemically reactive. I had not been able to make EIS at over 120 deg F that didn't oxidize. [Coffee maker hot plates are too hot] "Back in the day" conductive ion tracks forming using straight DC output was a much worse problem. Now the [Silver 9"] gen shuts down at 10 uS [PPM] where it isn't in over saturation at room temperature and additional PPM can be added simply by programming. With polarity switching, the ions tracks never form to 'be' disrupted. Best: Preheat the water to add conductivity without contaminating the water when conductivity is most needed in the absence of silver. As silver content adds conductivity, the water cools reducing reactivity. ode On Fri, Mar 31, 2017 at 9:30 PM, Top Dog <rsh...@gmail.com> wrote: > Unless I missed it someplace it doesn't appear to be an item for sale > anymore on the site. > > -Bob > > On Mar 31, 2017 9:15 PM, "Victor Cozzetto" <victor.cozze...@gmail.com> > wrote: > >> I strongly recommend the thermal stirrer with the Silverpuppy.
