Misconceptions About lons In Salt Solution

摘要

I was just reading your article entitled "Test The Salt Content Of Your Swimming Pool" (Silicon Chip, December 2008) and thought about using your technique at home. I was investigating further when I found a couple of articles stating that using an ohmmeter for testing will cause a molecular change within the salt solution due to the test current being DC, thus making the test invalid. I include a link to of one of the articles I read concerning this: http://blea.ch/ wiki/index.php/PPM_Meter.
