Hi Allan, You're doing a disservice by recommending the Hanna TDS meter for measuring CS PPM. It reads from 0-999 with + - 2% accuracy of full scale, which is + - 20 at any reading. As you can see it can be off much more than the reading of 5 to 15 PPM you are trying to measure. It is also a Total Dissolved Solids meter rather than a meter that will measure the conductivity of the CS. This is a useless meter for measuring PPM's.
What is much better is the Hanna PWT meter. It reads from 0 - 99.9 with 2% accuracy so you can see it will be off no more than 2 parts at any reading. It is also a conductivity meter which is just right for measuring the ionic portion of the CS. By applying a correction factor, this meter is a very good tool for the average person to have for determining PPM in colloidal silver. Please see our page regarding this meter for specs and more info. http://silvergen.com/ppm.htm Trem ----- Original Message ----- From: "Allan D Kruest Sr." <[email protected]> To: <[email protected]> Sent: Thursday, September 06, 2001 7:29 PM Subject: Re: CS>question..how to get the ppms you want > > > Teri If you will go to http://www.hannainst.com and bring up the web > page you will find their TDS 1 (Total Dissolved Solids) Meter that > measures from 1 PPM to 999 PPM of your C.S solution.
