Hi sol, what uS readings do you get? Mine vary all over the place, partly because I try to push the brew as close to the limit as possible. It can drop dramatically if you go too far past the peak. So I chicken out and quit long before I should. But I hope to automate the process as soon as the ozone machine is working. I'm working on the first draft of a paper that describes this new method. It is very illuminating since it tells just about everything that is going on in the process. I hope to get it posted soon. > A meter that isn't too far off, that gives consistent readings of > both my DW and the finished CS is more important than that it read > an exactly accurate uS.

Yes, that's true if you only want to check your cs generator, the calibration isn't real important. It's only when you need to compare readings with someone else on the other side of the planet. Then the problems start. It's the same issue as with TDS meters. The internal calibration can vary by a factor of two, and I get the feeling sometimes people divide instead of multiplying. So I try to avoid posts that talk about TDS readings. They are too confusing. > I believe Ode some years back had a similar experience to what you > described your friend had with two PWTs that gave very different > readings. Yes, I recall Ode's posts. Looks like the same problem again. I'm looking forward to trying the COM100. BTW, that was a good call on not using soap to clean the cs generator. You're right - that would be very hard to remove. I almost missed it but for your post. I almost never touch my system after the first cleaning with isopropyl alcohol. Maybe just occasionally wipe the silver off the cathode. Most of the time I just swap electrodes, and the black AgOH from the anode disappears when it becomes the cathode. How do you clean your generator and electrodes? > sol Mike M. -- The Silver List is a moderated forum for discussing Colloidal Silver.
