Hi Jay and Mike, The thing that scares me about the TDS-1 is that the accuracy is guaranteed at plus or minus 10 PPM. So if you are measuring a solution of 10 PPM the meter can read anywhere from 0 to 20 PPM and still be in spec as far as the company is concerned. Probably the wrong meter for CS production at any cost.
Best wishes, Andy From: M. G. Devour Well, Jay, there's value and there's value... The TDS-1 from Hanna Instruments is a good bit cheaper, but it reads from 0 to 2000 ppm. You'll be using it at the *very* bottom of its range, which means the accuracy will not be tremendous. Sorta like measuring grains of sand with a yardstick. Do you see what I mean?
