Robert,
In the recent past the list has covered this subject intensively. See the archives. Some time ago I was to taken to task "savagely" by a vendor on this list, when I cried "Foul and False" -- I had found a Hanna-like TDS-1 (sold by Hanna at the time for $15) -- sold as a "Colloidal Silver Tester" for $40 by -- go to Libertymall.com. It wasn't clear why this vendor, a prominent list member took me to task over this cry of "False" of mine -- except I believe he may use TDS-1 circuitry in his company's CS units. The $40 tester from Liberty is exactly the same as the $15 type. It is manaufactured by the same company in Portugal. After being savaged by this CS equipment maker and list member Vendor Fred, I put my money where my mouth is/was and ordered one. I didn't bother to respond to that individual's outburst!! And it's all in the Archives. Both units are a "dissolved solids tester" useful for solutions, like salt and water, and a solution by definition is when, say the salt, becomes an integral part of the fluid, or water, the salt's disssolved in. A true Colloid can not be a solution. There being lots of space between the individual chunks or silver ions immersed in the distilled water. This is my non techie definition. Lots of people are using the TDS-1 tester with their DW and CS and its
a guide only. Keep in mind you can get the TDS-1 to give you a reading
with anything -- pee, wine, soda, filtered water etc, etc.
I'm now onto my 4th type of CS brewer having had "Ole Bob's" technical help all along the way. Like many people I started with the Sota Battery model Zapper CS maker. I now have one that gives me a gallon in three hours at 10ppm, based on "Ole Bob's" ideas. He generously shares his ideas to all. If you use this simple TDS-1tester circuit for your own purposes -- its a guide and does the job in a way! Like me, you will along the way become obsessed with your CS method and eventually want a "better brew". The list's recommendation these days is the $50 PWT (being at least 10 times more accurate or sensitive than the simpler TDS-1), measuring in Micro Siemens. Your simple TDS-1 will, as you have suggested, give you an idea of your starting DW etc etc. Now, if you require a CS that remains clear and with a small TE or micro small chunks of silver -- you will need to start with the "best or least conductivity" DW. This resultant CS measured by a TDS-1, even when the water had a "zero" reading, may/will still be 50% above the real reading. Now the cruncher. I've had CS accurately measured to 12 ppm by a Spectrometer (Bob's) and the TDS-1 wil read "7". This brew was, and remained, and still is crystal clear. The smaller your silver ions -- the TDS-1 reading is well below the actual CS reading. Anyway, these are my observations for what they're worth. also, the purer/cleaner your DW, the less likely your CS will change color. Although I must admit a light Chadonnay hue is attractive in CS!! So the message appears to be -- if you start with reasonable water you'll get good CS. If you want to really know what you are brewing, then get the PWT (Pure Water Tester from Hanna). I still don't have one, I use a digital multimeter and that's not perfect and not as good as the PWT apparently, but good enough. Although I keep promising myself a PWT. New members should study the archives industriously for all the emails on this subject. In Silvation, Douglas Haack
