I'd like to know how your salt test can easily tell CS strength within 5 ppm AND be a "very subjective" test.
What quantities of salt are needed to test what quantities of CS and then with each given quantity what is the ppm? At 05:22 PM 10/6/2003 -0400, you wrote:

It's too subjective. > Trem Hi Trem, There are plenty of posts in the archives discussing problems with the PWT and getting it calibrated. Some people have even discarded theirs. How do you verify the calibration solution is still good? After collecting data from you, Frank, and Ivan, I'm now convinced it is a very valuable instrument, and I plan to get one soon. Then I'll attack the calibration issue. The salt test is very subjective, as you say. It's a quick test when nothing else is available, and it can easily tell the ppm in about 5 ppm increments. Often, that's good enough to tell if something has gone wrong with the process, or to see a change after adding H2O2 or vinegar to the cs. Or see if the Hanna has gone haywire:) We need all the crosschecks we can get to confirm everything is working properly. I'm now converted to the Hanna, thanks to your information. But I'll continue using the salt test when it is appropriate. Best Regards, Mike Monett -- The silver-list is a moderated forum for discussion of colloidal silver.
