Golly, that is the weakest salt test I have ever seen. It has to be well below 10 ppm. Can you try integrating the current vs time curve to get the average current, then do the Faraday calculation? An example of integrating a current/time curve is on my web page in Figs 3 and 4: http://www3.sympatico.ca/add.automation/misc/130vdc.htm The integral intercepts the right Y-axis at a value of about 32. The time is 30 minutes, so the average current is 32/30 = 1.066 mA You can do this in WPlot. Just give it a table of current values and the time since starting the brew. Just plug that into Mercury and let us know the predicted ppm. I'll bet it is pretty low:) Best Regards, Mike Monett -- The silver-list is a moderated forum for discussion of colloidal silver.
