Need a calibration solution for your refractometer?

Ok, so I don't even own a refractometer but many of you do. Here's a homemade calibration solution that you can make to calibrate your refractometers.

Hope that it will be of some help to you folks.

Thank you for this link (I read it from my chronicle when you posted it there as well.)

I don't have much faith in my own ability to make a perfect solution in a 2 liter bottle.

Come on, I know that you can do it. Just take your time and make two batches. If you did them right, the reading should be the same.

be nice if I could buy that salt, lol ours is mined under Detroit and called Windsor salt, do you think it would be the same? Good article Doc, no advil required

As long as it's only ingredients are sodium chloride and Iodine you should be fine. Just regular table salt.

Thanks Doc. I will check against this formula while the depression moves in and I get bored from being cooped up this weekend.
My refractometer instructions are to calibrate with pure water to '0' which I used my RO/DI and it seems to be on there even after a year so I am anxious to check it agaist the salt formula. Thanks for the link.
