You're right, but the key phrase is "after a fashion". To know what you have will *still* require you to have your CS tested by other means to establish a baseline for what your TDS readings actually mean. You'll need to send multiple samples through Bob B., CSPro, your local environmental lab, or somebody. In the end it'll end up costing you more than 20 bucks to do the additional testing, plus you'll also want to buy some calibration solutions along with the meter. You'll end up with a way to verify that you're still making it the same way over time. The problem is, if you change anything, run longer than you had tested, move the electrodes, etc. -- all bets are off, and your TDS readings will not necessarily be accurate with the new process. Anything that changes the particle size or (fill in the blank!) could affect the calibration of the readings. The only other thing you could do would be to exactly duplicate another person's setup who has done the outside testing, and then see if your TDS meter (using the same calibration standards from Hanna) gives you similar readings. In any case, it's at least useful for checking your distilled water! <GRIN> Be well, Mike D.
