Quick Overview

Why does BRS recommend this?


If you have been using a hydrometer and have never tried a refractometer then you should really invest in one.  They use much less water, and can easily be calibrated for accurate repeatable readings.  For the most accurate readings  you will want to calibrate the refractometer to the solution you will be reading, and that is why we always include a bottle of Aqua Craft Calibration Solution at 35ppt (1.026sg) to keep your reef tanks salinity spot on.


Must have equipment for aquarists! Easily and accurately measure the salinity of your tank. Simple to use and read. This unit automatically compensates for temperature. FREE Salinity Calibration Fluid included. Calibrating your unit ensures correct salinity readings.

*** 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.
Answer by: Bulk Reef Supply on Dec 23, 2013 11:14:00 AM
Is this unit calibrated specifically for seawater? Or seawater and brine. I was looking at red seas refractometer and theirs is calibrated for seawater only. I know that brine differs from seawater.
Question by: jeremy on Jan 17, 2016 7:09:00 PM
Great question!
The refractometer is set up for levels around 1.026 SG or 35 PPT. Unfortunately these are not designed for brine water levels. Feel free to let us know if you have any further questions!

Does this have an adjustable eyepiece? These old eyes require it to focus right.

Great question!
This will have an adjustable eye piece for focus. Feel free to let us know if you have any further questions!

what is the accuracy +/-
Question by: John Shannon on Mar 12, 2016 5:07:00 PM
Great question!
When calibrated the accuracy will be +/- 0.01 SG. Feel free to let us know if you have any further questions!

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.

 

*** Do not calibrate using RO/DI water as this will not give accurate readings***

  • Super and accurate! By FLSharkvictim on 5/6/2016

    I don't know how I been getting by with the Instant Ocean Hydrometer that I have been using for all these years! I finally broke down and bought the Refractometer. Wow, what a big difference between the two reading that i was getting.. I was getting a reading of 1.028 w/ the Hydrometer and w/ the Refractometer my reading was perfect 1.023, right where I like to keep my tanks at. If you're going to get into this hobby this is a must buy! HIGHLY recommended...
  • Accurate & Consistent Measurements By Paul on 5/4/2016

    Multiple measurements are consistent and with the 1.26 calibration solution they are accurate.
  • Great Price, Great Functionality.. It Just Works! By Patrick on 4/23/2016

    I had an old refractometer from another site that I had been using for years. Earlier this year, it started losing calibration between uses, so it was time to replace it. This refractometer was cheap, arrived quickly, and came with a bottle of calibration fluid to boot.

    Again, not much to say here... great value. It just works!
  • Works great By OnalaskaBill on 4/23/2016

    Easy to use and very accurate.
  • Excellent refractometer By Smo on 4/8/2016

    Well made, great optics, simple to calibrate and use.
  • A+ Product By Rick on 3/28/2016

    Quick, Accurate, and Simple... What more can I ask for??!!
  • Accurate Instrument By Boz on 3/20/2016

    Throw away your swing-arm hydrometer immediately and get a refractometer. Great instrument with two caveats. One, it needs to be calibrated often, as in, every time you use it. Second, the scale reads from 1.000 to 1.070 with lines every 0.001. It take a good eye to make estimate between those lines.
  • Great By Fred on 3/13/2016

    I was using a hydrometer at first but switched to refractometer and now I feel better about my readings. Very easy to use.
  • Must Have By Cave Man on 3/10/2016

    This product is very well built. It comes with a good case. This is a must have tool for the reef.
  • Quality and easy to use! By Adam on 3/9/2016

    Best thing I've bought for my reef in, well, forever. Super accurate and easy to use! I would definitely recommend to anyone in the hobby.
