I have been Reefing for over 15 years and have been using the old fashion hydrometers. After using a Refractometer I would never go back. Readings are so fast and there is no need to shut off mixing pumps to get a good reading. .

Only "complaint" is that it is much easier to read pointed at a bright light, so doing evening maintenance requires some squinting.

After years of messing around with those crappy hydrometers I finally went with this refractometer. I don't know why i was waiting. This thing is so much easier to use while being way more accurate. Incredible quality for the price. Get it today.

I picked one of these up recently, and was surprised with the quality of the Refractometer for the price! It arrived quicker than I expected, came with a sturdy hard plastic case that everything fits into perfectly. This being my first purchase from BRS I'm very impressed and will be shopping here more in the future!

Bought this after getting conflicting numbers from my IO hydrometer. This is easy to use and calibrate. I use it often as I'm starting a tank and have yet to even calibrate it. Takes a few seconds to measure and then a quick rinse w/ RODI and I'm done!
Great tool By christopher on 3/11/2013

Very easy to use and calibrate and accurate results. Used to use a swing arm hydrometer but after I started investing in corals I wanted something I could trust a little more and for the price the BRS refractometer can not be beat! I have had it now for at least 8 months with no issues. The most it was ever off was .001 which was fixed with recalibrating with the including recalibration fluid

This is a great tool for the home aquarium. Was using a small needle type meter and found it was a solid 3 to 4 points off. Tested my tank with this little beauty and I was right at 1.026. Glad I didn't add more salt. This tool os so easy to use my wife is willing to check the salinity as it only takes a second.

Hydrometer was way off By Anita on 3/2/2013
Anita would recommend this product to a friend
I just received my refractometer and calibrated to the fluid. Tested my aquarium and about fell over! The salinity was reading 1.015! According to my swing-arm hydrometer, it was 1.023. I only have one coral -a very forgiving star polyp - and my fish have been fine. So I obviously need to bring that salinity up. That POS hydrometer is going in the garbage!

Well constructed and simple to use. Just make sure you calibrate with the provided solution - there is a large reminder sticker on the box. So far, appears to work exactly as intended.

I've been reefing for 4 years and always used a cheap plastic hydrometer. I haven't seen great growth in any livestock. Decided to dive into this refractometer. Glad I did. My plastic meter read 1.025. Tried the refractometer and it read 1.030! Made the adjustment and everything is thriving. A must purchase for little cost!

You can't beat the price and the accuracy of this refractometer. The calibration fluid that is included is an added bonus. The lines are large and easy to read.
Not sure By Testor on 1/24/2013
Testor wouldn't recommend this product to a friend
Printed instructions with ATC unit say to calibrate with RO/DI water. When I do so, the readings on the ATC match the readings I get on a digital Hanna refractometer. However when I test the calibration fluid that came with this unit, it's reading is 1.028.
So do I assume the calibration fluid is off, or trust it, and recalibrate the optical ATC unit, and assume the digital Hanna is off.
I know BRS site says to use calibration fluid to calibrate.

I brought a Hydrometer from BFS and it worked great for about two months and then it started to give me reading i just know was off. I did a little research and got the refractometer. the best buy for reading the salinity for my water will never look back.
Simple, Soild, Reliable By Bryan on 12/18/2012

This is probably one of the best values for a refractometer. It's a rock solid unit with a professional case and dead on accuracy.
The included calibration fluid worked and I can confirm it registers the same parameter on an electronic refractometer. This should be the first item any saltwater aquarium owner should buy.
Solid as can be By Frederick on 12/16/2012

This refractometer does what it's supposed to do. It feels like a quality build and reads accurately. Just remember to use the calibration solution and do not calibrate to 0.00 or using ro/di water.
Calibration solution is great By Randal on 12/16/2012

This tool is great and consistent. Comes well packaged and feels well worth the money. The reason why I am not giving it a five star review is because the lines can sometimes be hard to read.

This is my first refractometer, and my main concern was the clarity of the markings, being a beginner in the saltwater realm. Not only was the BRS refractometer inexpensive, but it's very easy to use. Calibrating it was quick and easy, and the scale was very easy to read with the adjustable lens.

Easy to use refractometer. Like the precision a lot. Product really deserves 5 stars. One minor concern..the directions need more proofreading. (-1 star) Such a great product deserves 5 star documentation.

I had purchased a refractometer form another online retailer and when it arrived I was displeased to see it hadn't come with calibration fluid, or a nice microfiber towel. The BRS Refractometer is amazing, and should be in the top 3 things to purchase when setting up a reef tank.
Excellent choice By Charles on 11/28/2012

When you need to know salinity levels, a refractometer is the only way to go. This product does everything is it supposed to and it is easy to use, calibrate, and is very cost effective.

Every marine aquarist should have a quality refractometer and this one definitely fits the bill and the has a great price point. Having a refractometer also gives some peace of mind while doing quick salinity checks versus using a hydrometer that can be very inaccurate.

Just getting back into Saltwater after away 15 years. First item I have ordered from BRS or any online store. Saw it was offered at a great price and knew I needed to order it. Order was placed online on Friday 12/23/12. Receive it Monday 123/26/12. Better than expected. Refactometer is well built, nice weight and was easy to focus. Even got Calibration Solution with it. This item I would recommend to anyone wanting a quality product.

It's my 1st refractometer it seems great and accurate. I have 20/20 vision and the only complain I have is I wish it came with bigger number chart , maybe a better zooming, or a scale running SG 1.015 - 1.035 or 1.040 , but still a great product.
