Hi Katarina, Bill will set you right with multimeters, and if you can hang on a bit longer I should be in a better position to advise on the use of cheap conductivity meters (reads in uS) for the direct measurement of silver ion concentration. I want to run a couple more correlation tests and try to establish the requirements for accurate readings. This will enable you to perform the same tests that I believe Fred does. (must congratulate him for providing this 'gratis')
Until then...
