This certainly can be used to double check the Milwaukee refractometer. You will want to use RODI or distilled water to calibrate the refractometer, but you can always use the Aqua Craft Calibration solution to reference the reading to 1.026 sg.
Aqua Craft Salinity Calibration Fluid calibrates to sg 1.026 or 35ppt.
Excellent product! By Carmen on 12/24/2016Carmen would recommend this product to a friendHighly accurate.
Good but messy By Aaron on 11/25/2016Aaron would recommend this product to a friendI bought this, like everyone else does, to verify my refractometers calibration.
After having calibrated it with RO/DI I was shocked to see that it was off. Certainly this is a good investment to make sure your equipment is giving you the right readings.
My only problem with it is that it is messy. The bottle has a dropper cap to allow you to add only a few drops of the solution at a time. The problem is the dropper cap is loose and when the bottle is squeezed, even with the lightest pressure, the solution dribbles out of the sides of he cap.
The bottle is big and has plenty of fluid but it does make calibration time a bit messy. Certainly this is not a varsity level applicator. I will not buy the brand again.
Must have item By Dan on 9/4/2016Dan would recommend this product to a friendAlways a good idea to calibrate the refractometer occasionally. This is handy and more accurate than trying to mix my own calibration fluid.
Does the job By Fred on 5/1/2016Fred would recommend this product to a friendThis fluid is what it's supposed to be. Not too difficult to explain. The benefit of having it tho, is that your refractometer (analog or digital) will always be on point. Calibration from 0 with RO water isn't that accurate. Even the best test equipment is useless without a standard to calibrate with or compare against. For the hundreds and thousands of dollars that go into having a tank, less than $10 for this fluid is a more than justifiable purchase.

Must have product By Michael on 7/29/2015Michael would recommend this product to a friendI am old school to say the least and always used RO/DI to calibrate my refractometers. Well I admit that method doesn't work !
Order this product and you will know the truth. Both of my meters were off by as much as 4 points. Now I am confident that my salinity is correct.
Plenty of fluid and the dropper style top is great
Great product By Ed on 7/25/2015Ed would recommend this product to a friendFrom the bottle design to the quality of the fluid, everything is great.
Aqua Craft Salinity Calibration Fluid By Salty Dog on 6/1/2015Salty Dog would recommend this product to a friendExcellent product for the $$. Should have purchased months ago instead of having my refractometer checked periodically at the saltwater shop.
