The PWT will do if you are always producing the same ion to colloid ratio and you know what that ratio is. Many things can affect that ratio even with the same generator and that ratio will often change even in the same batch. That means the meter reading will and does change. The inherent internal inaccuracy of the PPM/TDS meter gives one a feeling of repeatable sanity [by smudging the fudge factor into recognition] It 'says' something understandable much like "The cow pattie is lying on the ground and smells like fertilizer...not 3 to 9mm above it containing a 20% to 80% nitrate to sulphur ratio" The PWT can be useful but still isn't going to tell you all that much with a high degree of accuracy especially when comparing different processes. Still, it gives you a 'clue within some range' [like quantifying a hunch] and it's worth having. Beats nothing at all. I have both the PWT and the PPM/TDS meter. They rarely agree on anything but argue quietly with my taste buds and laser pointer. I use them for entertainment. [entertaining the idea that I know what I'm looking at] I won't poke out my eyes because they can't see infra red. Ken
