*** Do not calibrate using RO/DI water as this will not give accurate readings***
All my water is from RO/DI water, how do you calibrate this?
Question by: Larry on Dec 23, 2013 11:14:00 AM
Hey Larry,
You calibrate it using the included 35ppt/1.026 calibration solution. The solution is a known standard, so you put that on the slide and then adjust the refractometer to 35ppt/1.026.

Full Details

Refractometers are one of the best pieces of equipment an aquarist can purchase. It not only ensures accurate measurements of salinity but it is also infinitely easier to use and read.

 

Comes with the following:

 

  • Dropper
  • Carrying Case
  • Screw Driver for calibrating
  • Adjustable eyepiece
  • Salinity Calibration Fluid. Calibrates to sg 1.026 (35ppt)

 

Steps to calibrate your unit:

 

1) Using the dropper place a few drops of the solution on the glass and close the lid.

2) Looking through the unit and turn the screw until the unit reads sg 1.026 (35ppt)

3) Screw the cap back on your calibration solution for storage. It is important that the cap is on tight or water will evaporate and ruin the solution.

  • Simple easy to read/use product By RAMON on 5/17/2015

    I Just used my new REFRACTOMETER for the first time, after years of using a basic hydrometer for checking my salt levels. I was surpisurprised at how simple it was to set up , calibrate and use. I assumed that since v it is more precise and scientific then a hydrometer it would be tuff to use. But with included instructions it was an ease to use. I definitely recommend this product.
  • MUST HAVE! By Gerry on 5/14/2015

    I had to get use to how to read the blue line at 1st. After playing around with my lighting and found the right angle that makes the blue line super clear I was 110% satisfied with my purchase. I feel I really trust my measurements and my old hydrometer was way off!
  • Perfect By Steve on 5/5/2015

    First purchase of a refractometer and am more than pleased!Easy to calibrate and easy to use.BRS sends enough calibration fluid for life too!
  • Accurate By Jack on 5/3/2015

    I decided to get this as it was on sale. Well to my surprise this was very easy to calibrate, and accurate. My plastic hydrometer was measuring 1.020 all the time but it was actually 1.025 by the refractometer. I can trust this meter.

  • Way better than a swing arm hydrometer By Thomas on 4/26/2015

    I've been using a swing arm style hydrometer for the longest time now and was always concerned about salt build-up around the arm and it messing up my readings. I finally decided it was time to upgrade and man do I love the refractometer. The included calibration fluid is super easy to use. The only qualm I have with it is, it can be difficult to get a precise measurement such as 1.0255 because the measurement lines are pretty close together. Looking through it a very bright light improves its readability though.
  • satisfied By JOEPIT on 4/23/2015

    just happy with the product .
  • Great product By Happy reefer on 4/21/2015

    It's easy to read and use; I liked that it came with calibration fluid.
  • Good item for the price By Clmarti78 on 4/18/2015

    We had been using the hydrometer for the last couple years and it seemed to be doing well. We got this due to all the things we have read about the accuracy being better with a refractometer. Unit was easy to calibrate and works as it should. I do have a little bit of a hard time reading it but my wife has a better time with it so it could be my eye sight. If I knew another brand would be easie to read I would definitely spend the extra to have it. But over all for the price great buy for a step up from the other reader we had.
  • Great Refractometer. By onefang on 4/15/2015

    This is well built, holds calibration ( BRS is cool enough to throw in some calibration fluid). I purchased a more expensive unit and it wouldn't hold calibration.. this one is rock solid. Buy it!
  • Works Well By Tim L on 3/31/2015

    Bought this because I have 2 Hydrometers that don't agree and needed a measuring device I can trust. This is easy to use and clean.
  • Accurate Salt Readings By Gabriel on 3/24/2015

    Good value, nice that they include calibrating solution and a nice case, straight forward instructions. Really every marine tank should utilize one of these and at this price its almost half what my lfs sells them for.
