The meters put out by Hanna Instruments and the like measure only the ionic content of CS. They're not "worthless" but they don't tell you PPM either.
If you send a sample to a lab and record some idea of the TE [Tyndal Effect] and take a meter reading first, you might be able to have an 'idea' of subsequent batch strength via a guesstimated fudge factor for your process. [assuming that it's repeatable to some degree]
Get a laser pointer to see the TE.

The less the TE, the more close the meter will read to the actual silver content.

...something like...15 PPM on the meter and a 'medium' bright TE = [more or less] 18-22 PPM

Any chance there's a nice, easy to read meter that measures PPM's? Somehow, I know there's no such thing, but have to ask.
