Hello Gary, Until someone comes up with the relationship between conductivity and PPM of silver, it is all a ballpark best guess.
However, the meter has a lot of other uses beside trying to guess at the concentration of EIS. If you purchase distilled water, how do you know it is of high quality? If you distill your own water, how do you know its quality? When you rinse out your jar and are ready to brew a batch, how do you know there is no contamination in the jar? If you bottle your EIS, how do you know the bottles you use don't add extra things to your EIS? How stable are the ions in your EIS over time? All of these questions can be addressed with a meter. The most important one is the purity of the water followed by the purity of the jar you are making your EIS in.

I will use the information I got from the man who schooled me on making EIS and just go with the amount of time. Ballpark is good for me. ------------------------------------------------------------------------------ From: Neville Munn <[email protected]> To: [email protected] Sent: Mon, March 8, 2010 7:38:27 PM Subject: RE: CS>Silver Meter [Any comments on this is appreciated] -Sure, here's my thoughts on the subject... [...basiclly has the same component inside as the Hanna PWT.] -That'd be their way of saying "there isn't a meter 'off the shelf' that is specifically designed to measure EIS" {without actually saying it!} cos to my knowledge...there isn't. Meters used for EIS purposes are...'guesswork using a measuring instrument'. I got three meters and none of them are 'accurate?', but they get me in the ballpark, which is only where I need to be. I know from laboratory analysis that I got more *total* silver content than all my meters show, but the meters fool me into determining *roughly* what silver content I have and that's all I need to know <g>. My question would be...How 'accurate' do you wanna be, or *need* to be? Without laboratory analysis meters are only going to get you *in* the ballpark, *you'll* have to pick the seat you think is the *best* seat once you get *in* {using all that information about meters, calculations etc etc available in the public domain}.

Someone told me you needed the Hanna PWT that costs about $60. I found a Hanna Primo for half that. The fellow that told me about the PWT says he checked the Primo and it wasn't accurate. I contacted the company that sold it to me and they said it basiclly has the same component inside as the Hanna PWT. I would like to be able to be fairly certain what ppm I'm making. Any comments on this is appreciated. -Thanks Gary Native American style flutes & Matted photos by ~ Gajon ~ www.etsy.com/shop/gajon ------------------------------------------------------------------------------ Download a free gift for your PC.
