I do not see anything about a conversion factor in the meter directions. Am I missing something?
In the directions that came with the generator, to says: If you want to know the exact PPM of your CS, we suggest ordering our PPM tester. It is accurate to 2% and will also check your distilled water for mineral contamination."
It sounds like there isn't a conversion needed, and that you test PPM directly with the meter they sell.
