<snip> > 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. > Both conductivity testers and TDS testers are the same item, excepting that the TDS tester converts the microSeimen reading (multiplying from 0.5 - 2.5 depending on the testers TDS factor) to ppm TDS. A true colloid can not be a solution...true enough, but clear CS sits upon the dividing line between a colloid and a solution (0.1nm) and may exibit the properties of a solution. > > 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!! > The TDS-1 has a TDS factor of 0.5 and so a reading of 7 is equivalent to 14uS. 14uS being a reading of 12 ppm is a good correlation to that I and others have found in clear or lightly coloured CS, witness Trems' blatant sales pitch recently posted. > 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. > Indeed.
