It will require some checking against some known ppm CS to see how accurate it will be, but if several of us have these, we can network and figure out how accurate they are, and be able to get a close ppm reading, which is fine for what we are doing. It will definately help us to keep each batch to within a few ppm of each other. Just my imput and thoughts! Take care! Jim Einert, N.D.
