Salinity Meters and correct measurement

[borillion_star]

Im purchasing a digital salinity meter that measures in Units of measures in μS/cm, mS/cm, ppm, ppt, mg/L, and g/L.

We use ppm right?

Man unless it's free I would advise you to not buy that and get a simple but quality refractometer. For $35-45 you can get one that needs less maintenance and is super easy to use. Just rinse with rodi when done.

Also does TDS. Honestly I found one someone is willing to part with for not much more than a high end refractometer so I was like I don't have much to loose.

Actually your right lol, I just stumbled onto this http://www.reefcentral.com/forums/showthread.php?t=920012

It can not measure high enough to be any good.

Saltwater is at 53 mS/cm, and you're probably right about the device not necessarily reading high enough levels, but you could check the specs. I used a salinity meter and liked it, but a refractometer is fine, too.
