Hi Gordon, from what I have seen posted on this list, you are right to distrust Hanna's TDS meter for silver ppm. What has been recommended is the Hanna PWT meter with a small conversion factor,- - see a post below from May about this subject, Jack ** Date: Wednesday,May 29,2002 10:32 AM Subject: CSTDS-1 versus PWT for measuring PPM Hi James, I don't mean to jump in when you addressed the post to Dean but the fact is that the PWT reads CS much better than the TDS-1 for several reasons as pointed out on our website. Also, you do NOT divide by half when using the PWT. You ADD to the reading. In the case of our generators you add 20%. Hanna is right in telling you to cut the reading in half IF you're measuring dissolved solids such as minerals in the water. However, we as CS users are interested in measuring the content of CS to determine what silver content we have. In this case the meter only measures the ionic portion of CS. And that reading is always less than the total amount of silver content because the meter will NOT read the colloidal portion. Therefore one has to add to the reading to get the total PPM. The correction factor will be the difference between how much of the mix was colloidal versus ionic. We have had our CS analyzed by atomic absorption spectrophotometry and it is generally always the same ratio. Another thing I forgot to mention is the fact that the TDS-1 has an accuracy tolerance of + - 2% of full scale. Since the TDS-1 reads from 0-999 that's + - 20 PPM. Since the PWT reads from 0-99.9 and has the same percentage of accuracy that's + - 2 PPM. And the PWT gives you a decimal point in the reading while the TDS-1 reads in whole numbers only. I hope this helps clear up some of the controversy about the TDS-1 versus the PWT. The PWT is the best choice hands down for measuring PPM. Trem www.silvergen.com http://www.silvergen.com

tom, The main website is: www.hannainst.com bu the PWT is located at http://www.hannainst.com/products/testers/pwt.htm I have one and am not impressed. It doesn't seem to work.

Re: CS[Ralph] CSTest equipment
The PWT is very useful. It's the TDS you don't want. You need fudge factors to approximate your ppm though. Chuck If I melt dry ice can I swim without getting wet?
