TDS Meter Reccomendation

[Lizardgi]

So I'd like to pick up a TDS meter to ensure I'm making clean water with my RO unit. I've seen [ame="http://www.amazon.com/HM-Digital-Pocket-TDS-4-Quality/dp/B0002T6L5M/ref=sr_1_1?s=home-garden&ie=UTF8&qid=1297201640&sr=1-1"]this one [/ame]on Amazon, but I don't see any option to calibrate it. Does anybody have experience with "cheap" TDS meters that don't have a calibration option?

All TDS meters can be calibrated (it's usually a little screw you turn), you just need to buy the calibration fluid separately. I got mine off of Ebay for about $15, and the calibration fluid was another $4. Be sure to get the fluid that corresponds to sea water.

Biff, are you sure you are describing a TDS meter? Because that sounds a whole like a refractometer . . .

Lizardgi the one you linked to, looks like an acceptable one.

These work well too.

Biff is thinking about her sick Candy Canes and her order sitting at the airport.

Yes . . . that would be distracting . . . .

Thanks everyone, I'll probably end up going with the linked one - although the always connected ones look quite nifty as well...
