Re: CSTesting PPM of ionic silver
Ken, I'm sure glad you know how to tell the difference, and left all the good stuff! And thanks for confirming my figure of a 60% drop in conductivity with your own measurments of 65%. That shows the problem is real and affects everyone. Thanks, Mike Monett Ode Coyote odecoy...@windstream.net wrote: Hogwash deleted.

Re: CSTesting PPM of ionic silver
Both meters measure conductivity and particles aren't conductive. You have it backwards. Meters detect ONLY ionic content. The PWT doesn't run the conductivity number through an equation meant for salt water. Roughly double a TDS number to get what a PWT says. No meter will measure PPM, but the numbers are about the same between a devise that will measure PPM and conductivity readings from a meter that won't at around 10-12 uS =10-12 PPM.after the conductivity stops dropping.

Re: CSTesting PPM of ionic silver
I missed Melly's post so I will reply through here. TDS meters can have different calibration depensing on the application. One is a factor of 2 different from conductivity measured with a pwt. The other calibration is a different number. You often cannot tell which number was used to calibrate the TDS. So you cannot simply double the reading. If you have a pwt also, simply measure the cs with both meters and take the ratio. This will tell you what the calibration factor is. You most likely have some silver sulfide tarnish on the electrodes from automobile combustion and other sources. This releases sulfur ions into the solution during the brew and can significantly disrupt the brew. The sulfur contamination cannot be detected with a pwt. By far the best way to detemine the quality of your cs is with the Salt Test. It is immune to the contamination and will give you a direct indication of the silver ion content. Please see the following link for more information. http://health.groups.yahoo.com/group/silvercentral/message/560?l=1 Thanks, Mike Monett Ode Coyote odecoy...@windstream.net wrote: Both meters measure conductivity and particles aren't conductive.
