When you compare units also compare what you get for the price. While the prices of units may look similar, the actual features and included items can make a difference in the total price.

I have both a handheld and an in-line TDS meter. I love both, but I rely on the in-line and rarely use the hand-held much anymore. You can get either at aquariumwaterfilter'w web site
Please note, I am their webmaster and therefore "affilaited".

Can someone point me to where they found Eric's powerpoint presentation on the sites cited in the PDF file? <A HREF="mailto:[email protected]">[email protected]</A>
