I need to have distilled water of no more than .4 uS, which is lower than a TDS can read, so I was lucky to have chosen a PWT 3 years ago. Commercial distilled water of all brands that are available where I am read .6 uS to well over 2.5 uS. Most people (I've been told) can make very good clear CS with distilled water that reads up to 3.0 uS, but I can't. Depends on conditions where you are. sol Deborah Gerard wrote: > using your TDS what measurements are you looking for....TIA...deb > > sol wrote: > > Most distilled water is produced *locally* to where it is sold. > Therefore, it is necessary to try various brands in your area, and > see > which one works best for you, or is the least conductive when tested > with a meter (PWT, TDS, COM-100). > Commercially sold distilled water can also be quite variable within a > brand. > sol > > . . wrote: > > > I'm wondering what brand of distilled water is the purest... ??? > > > > > -- > The Silver List is a moderated forum for discussing Colloidal Silver. > > Instructions for unsubscribing are posted at: http://silverlist.org > > To post, address your message to: silver-list@eskimo.com > > Address Off-Topic messages to: silver-off-topic-l...@eskimo.com > > The Silv! er List and Off Topic List archives are currently down... > > List maintainer: Mike Devour > > > >------------------------------------------------------------------------ > >No virus found in this incoming message. >Checked by AVG Free Edition. >Version: 7.1.385 / Virus Database: 268.3.5/301 - Release Date: 4/4/2006 > > -- Whenever you find you are on the side of the majority, it is time to pause and reflect.
