  • From Tery at 8/24/2015 9:42 PM
    • How do I use this? I drip it onto my refractometer and what should it measure to? Should it be 1.026 or is it 35ppt?
    • Tery,
      You can calibrate it to either 35 ppt or 1.3394 on the refracting index scale.

  1. Do Not Use, Not Correct Index Review by Earl
    Product Rating:

    As mentioned, I had always used RO/DI water to calibrate and never had a problem and matched what others got. So I bought this to make sure I was doing it correctly. After I calibrated both of my refractometers they both showed RO/DI water as -2 points below zero. I knew something was wrong at that point. I ended up buying a digital refractometer and sure enough, this stuff is way off as seen in the photo below. It's a total waste of money and will have you running your salt levels 2 points higher than you want. All I can guess is that some has evaporated and as a result, WRONG.

  2. Handy to have Review by Mark
    Product Rating:

    I always calabrated my refractor with RO/DI water. Then I was told to use this. My refractor was off by a couple of points. What I thought 1.025 was only 1.020. Now my salt level is backup where it should be. (Posted on 7/21/2015)
