Found One.
 

I'm looking for a TDS meter in Calgary. I know ocean city has some but 40 bones for a hand held and 60 for a "in-line" seems pricy to me....Anybody have a spare one or know where I can find a cheap one in Calgary? Either a handheld or one I can hook right up to my RO unit. Doesn't matter what kind.

NEVERMIND! Got one. Thanks.
