Decided to bite on one of these (search on ebay for salt-3000) ..... seems to work OK, but I haven't confirmed readings yet with strips and my pool shops measurements. The strips cost $1.15 per test now locally tho results seem close (+/- 300ppm?, if fresh) compared with my shops results. But at that price I wouldn't test salt levels every time I pull out the Taylor Kit, even though I would like to.
They really are just testing for TDS ..... the manufacturer HM Digital states this, and doesn't seem to be aggressively marketing it for pool salt level testing.
Any one have any experience with these units? Opinions?
