Hi, Bruce & All! We also have purchased and are using the TDS1 from Hanna Instruments. We haven't yet figured out how you can get readings as "fine tuned" as 23 ppm or 13 ppm. Our readings go from "0" to "1" to "2" without anything in between. When our CS was a light golden yellow it registered a "1" and when it was a deeper golden yellow it still read "1". We are multiplying these values by ten to arrive at the 10 ppm and assume that both of our batches are somewhere between 10 & 20 ppm.... I know that the second batch of CS was much stronger than the first, but our reading didn't change. What do we need to do in order to get the finer reading? ( We have the callibration packets and are using them.) Any enlightenment would be much appreciated! Thanks in advance.

I used a Hanna TDS1 to check some Sure-Fine "Distilled Water', bottled in Little Rock, AR, and it tested at 23ppm. I switched brands bought at the same store, and got distilled water at 1ppm. So it ain't all the same folks!!! Jim Einert, N.D. -- The silver-list is a moderated forum for discussion of colloidal silver.
