  • Simple to use and should last for a very long time. By Scott on 3/4/2015

    Simple to use and should last for a very long time.
  • Great item. By Michael on 2/9/2015

    Works spot on.
  • Simply works By Jesus on 2/3/2015

    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.
  • Small investment saves your peace of mind By Martin on 12/15/2014

    If you have a refractometer, don't hesitate in buying this. I have two and they both read 35 ppm as advertised. Don't use RO/DI...I tested and calibrated my refractometer with RO and found that at about 35 ppm my refractometer was reading out by 3 ppm. With this calibration fluid I know I'm reading my salinty accurately at the range it needs to be accurate.
  • BOTTLE SHOULD LAST YOU A LONG TIME By Mark on 11/18/2014

    I like the fact that it has a build in dropper. My refractometer came with a small vial of calibration fluid but no dropper! I have to use my dropper for doing other water tests so always making sure it was completely clean of any old saltwater just added another step to my calibrations. Plus if you're using two drops or so to calibrate this should last you a long time. The bottle was much bigger than I was expecting.
  • Good Value By Mario on 10/14/2014

    The calibration fluid is easy to use and works as advertised.
  • Great Product By Bryan on 4/24/2014

    It's easy to use and very accurate. Does a better job than RODI water.
  • Recommend By DE on 3/3/2014

    You need to calibrate refractometer with a solution ode to what you are testing.
