Excellent product for the $$. Should have purchased months ago instead of having my refractometer checked periodically at the saltwater shop.

Very accurate. Dropper tip on the bottle eliminates having to use a pipet. Enough in the bottle to last a very long time.

Perfect solution for calibration of your Refractometer. Don't make the mistake I did buying the Pinpoint Salinity Calibration Fluid it is for salinity probes not Refractometer. Keep the fluid stored in a cool place you don't want any evaporated fluid.

I use this solution weekly to keep my refractometer and probes calibrated. Peace of mind that my readings are true and I will not test without it. Good stuff!

My new refractometer was off 3 points using RO water to calibrate. Now I know it's on with this calibration solution.

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.
Excellent Product, Excellent Accuracy By AsmoTiC on 1/26/2015

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.
