- Refractometer for Reading Salinity with Calibration Fluid
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.
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.
Range: 1.000 - 1.070 SG
Comes with the following:
- 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 for saltwater aquariums***
Great product By Trever on 12/24/2017Trever would recommend this product to a friendEasy to use. Easy to calibrate. Glad i bought it.
Great! By MikeForce on 11/22/2017MikeForce would recommend this product to a friendAwesome accurate tool. Always use it to make sure my probes are on point.
Works great but hard to read with glasses. By Brian on 9/20/2017Brian would recommend this product to a friendThis is great but I wish the eyepiece was larger or somehow better suited to reading with glasses.
Works well By Nick on 9/18/2017Nick would recommend this product to a friendVery easy to use
I like that you can calibrate it! By sh4rkbyt3 on 9/14/2017sh4rkbyt3 would recommend this product to a friendWanted to check the accuracy of my Instant Ocean Hydrometer after reading a few less than good reviews and some complaints on a few forums. Well having to be honest, the hydrometer was spot on in it's accuracy.
One thing I've dealt with through the years is the "know it all's" who seem to think what they use or how they do it is the best. Sometimes that's true but a lot less than you'd think.
This was one of those points I proved to myself. The hydrometer is just as accurate as the refractometer! It's good to be able to check for accuracy though and have a reference point.
Very good product By Troy on 9/5/2017Troy would recommend this product to a friendExtremely accurate and well built.
Great Buy ! ! By Fudsey on 6/25/2017Fudsey would recommend this product to a friendThis is my 1st Refractometer and I love it. It works great and although it may seem hard to see in some light, just reorient yourself to the light and it becomes clear. Just be on the safe side, I calibrate it every time and usually it is spot on. Only had to adjust it a few times.
Good By Nick on 5/11/2017Nick would recommend this product to a friendDoes what it's suppose to.
Love it By DW on 4/21/2017DW would recommend this product to a friendWent from 2 instant ocean hydroneters tbat read different numbers consistently. Not just different from each other, but even after tapping bubbles out I'd never get the same two readings...
Yea, I'm good..
Got this guy and love it. Only complaint is I should have purchased it sooner
Fantastic product By Lerch on 4/2/2017Lerch would recommend this product to a friendThis is my first time using a refractometer and I love this product. Very accurate and easy to use. I no longer worry where my salinity value is at.
A Necessity By Michael on 3/31/2017Michael would recommend this product to a friendBeen out of reef keeping for over 10 years. Starting back up and bought the usual floating dial salinity monitor as I was use to. Saw the great price and had to quickly upgrade. So glad I did salinity levels were not even close floating needle when filling tank said 1.025 checked it with this after quick calibration check and found I was only at 1.021. Glad I was only starting the tank and not relying on the cheap gauge when I begin to add aquatic life to the tank.
Much better than Red Sea By Michael on 3/25/2017Michael would recommend this product to a friendI had the Red Sea refractometer and was concerned that it could lose calibration in minutes. This unit is much easier to read, feels better built, better price, and seems to hold calibration better. Highly recommended.
A great demo on the Milwaukee Digital Refractomete ...

All my water is from RO/DI water, how do you calibrate this?
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.
Thanks for getting in touch with us in regards to calibration solution for this refractometer. You can purchase more of this on the page that I have linked below. I can say that the included bottle of solution will last quite a while. Please let me know if there is anything else that we can assist with. Thanks!
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!
This will have an adjustable eye piece for focus. Feel free to let us know if you have any further questions!
These recommendations from the manufacturer are due to the temperature at which the refractometer was calibrated, and in the case of the fluid, the normal aquarium salinity at the typical aquarium temperature. In the case of our use, the temp of the fluid sample will rapidly match the temp of the refractometer, and as these are ATC units, they will adjust for minor temperature differences. What we recommend is that you keep and calibrate your unit at the temp (most likely room temp) at which you will normally take your readings, and try to use a consistent light source as well.
Sorry about the typo there, and thanks for bringing that to our attention! That should actually read accuracy +/- .001 SG!
