where can i buy a TDS meter?

[denverfishguy]

I purchased a RO/DI unit and need to test its effectiveness. Where can I pick up a TDS meter? Any info is appreciated.

got mine off e-bay for $25. I purchased one of the $75 - 6 stage rodi kits but cannot remember the name of the seller. He didnt list TDS meters but I e-mailed him and was able to purchase it when I got the rodi. I remember seeing other e-bay auctions for tds meters.
Good luck,
John

Airwaterice throws in a free TDS meter when you purchase a Typhoon. Now thats a deal. Free $30 TDS meter.

www.reefgeek.com has both the handheld and inline versions of tds meters for $30.

^ That is the page with the TDS meters. It's in the water purifier accessories.

Note: we posted at the same time I guess, yes that is the cheapest I've seen the inline one for. In fact I've seen it for like double that on a site that claimed specifically to have it cheaper than anyone. :shrug:

Does anybody have this unit? Is it a pain to calibrate?
