refractometer calibration
I've always calibrated my refractometer using plan old RO water and although I knew some error would be involved I was under the impression the amount would be so small it would not make a difference. However I keep hearing more and more lately people stating after reading a few articles that this isn't the case and you need to calibrate your refractometer with some kind of calibration fluid otherwise you'll be off a noticeable amount.
Just wanted to share that after receiving some PINPOINT Salinity Calibration Fluid to calibrate my conductivity probe I stuck some in my refractometer and it's it reads exactly 1.026 as it should, not even out the slightest bit as far I can tell. So regardless what articles my suggest it seems I can conclude that RO water is certainly an acceptable calibration solution. Anyone else try this and get similar or different results?

Yes, my refractometer came with 18 megaohm water(pure) for calibrating at 0, I compared that to my RODI and it was the same, I bought calibration fluid after reading (probably the same) an article and checked the calibration and yes it was correct. All 3 gave the same results, so now I can use my RODI water to check my calibration fluid.

What is calibration fluid? Sounds like RO water in a fancy container with a pretty label for a stupid amount of $$$. Somebody always out to make a buck...lol Good to know this has been double checked, I always use RO water to check mine. Thanks for posting....
