Here's a thought. A cheap DMM coupled to a pair of wire electrodes, uniformly spaced at say 1/2", with a uniform exposed length in each wire of say 1". You will get some resistance reading. To equate it to a nominal PPM, it will need to be calibrated against a batch of CS of known PPM. Maybe a knowledgeable list member can suggest a commercial CS whose PMM is accurately known. regards, Kevin Some further thought: As stated by others, accuracy assumes your brewing process produces mostly ions, not particles, but that seems pretty well gauranteed. Also, that you have not used any CS brew starter such as salt. That could be taken care of by doing before-and-after readings. The wires will have to be maintained clean - ie no oxide film or scum. Stainless steel welding wire from a welding supply probably best for that. Also, note that resistance measurements give a result inverse to PPM. If you can't handle that, then try reading milliamps with a battery in series - that should give a proportional reading (but I see that Harold MacDonald warns against cheap DMM's in that area).
