Always 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 5/1/2016

This 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.

I 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 7/25/2015

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