Easy to use, large quantity, and the drops come out at a very controllable rate. Tested this against multiple calibrated devices including the Milwaukee MA887. All read at 35, so it's pretty dang accurate.

I actually ordered this on accident. I didn't realize the Refractometer was going to come with a bottle of the same stuff, so I ended up with two.
As it turns out, this worked out great. My sality was so far off from the Hydrometer I was using before, I thought something was wrong with the Calibration Fluid that came with the Refractometer. This bottle was a perfect match for the fluid that I calibrated my Refractometer with the first time and gave me piece of mind on the accuracy of both.
Best Price for a bottle that'll last forever By Ryan on 1/15/2015

My refractometer came with enough to calibrate it once. This will last forever and I'll know my salinity is perfect.

If you have a refractometer, don't hesitate in buying this. I have two and they both read 35 ppm as advertised. Don't use RO/DI...I tested and calibrated my refractometer with RO and found that at about 35 ppm my refractometer was reading out by 3 ppm. With this calibration fluid I know I'm reading my salinty accurately at the range it needs to be accurate.
BOTTLE SHOULD LAST YOU A LONG TIME By Mark on 11/18/2014

I like the fact that it has a build in dropper. My refractometer came with a small vial of calibration fluid but no dropper! I have to use my dropper for doing other water tests so always making sure it was completely clean of any old saltwater just added another step to my calibrations. Plus if you're using two drops or so to calibrate this should last you a long time. The bottle was much bigger than I was expecting.

It's easy to use and very accurate. Does a better job than RODI water.

You need to calibrate refractometer with a solution ode to what you are testing.
