Refractometer

[Readingexcalibur]

Am looking at buying a refractometer. This is what I found off a google search. I do not have PayPal so no eBay for me. If this is not a good one, can someone link me to one.

not forget calibration fluid

Bulk Reef Supply has one I use for about $30 and it comes with calibration fluid. There's almost always a group buy going on you can jump in on to get a little discount as well.

I was reading you don't need the fluid, that RO water works

I calibrate mine with RO/DI. I also have a digital refractometer. I see no reason to have one that is a telescope that requires a light source to see my salinity when I can see it given to me on a digital screen.

The only reason I've got is price. 50$ or 100+$ is a big difference if I'm going to get the same results.

Alright, bought one from my lfs. Pretty excited, now I just need to go get some RO water to calibrate it. Do I need RO or RODI for calibration. Just wondering.
