Not sure By Testor on 1/24/2013

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.

Forget your little floaty tool. This couldn't be easier to use or more exact. Every reefer needs one of these!

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.

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.

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.

Very easy to use. Easy to calibrate. Much more accurate then swing arm type hydrometer. Wish the eyepiece was a little bigger, but stil a great product.

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.
Great product...so so instructions By DANIEL on 12/1/2012

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.
Nice for the price By brian on 11/30/2012

Very easy to read compared to my Marine depot refractometer. And comes with calibration fluid. It does what it claims.

Got one of these at the BRS Black Friday sale. Easy to calibrate and read. Like it a lot better than my old encrusted Instant Ocean hydrometer.
Best purchase you can make for salinity By william on 11/28/2012

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.
Great Product By Clayton on 11/28/2012

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.

Excellent product. Well made. Product is solid, much heavier than expected, not some cheap light plastic thing that I've seen before with other places. Comes with a nice case. Very pleased with this purchase.

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.

There is no better way to measure salinity than with this refractometer. I proceeded to calibrate after receiving unit with included calibration fluid.

Great item and a very necessary in the reefing hobby, not to mention the bargain price.
With this I was able to find out how much my salinity was off compared to my floating hydrometer which had slight calcium build up on it.
