A refractometer is used to measure the density of a solution, in our case how much malt sugar is in solution.

Featuring both a Brix scale AND a Specific Gravity Scale
Our refractometer is unique in that it features both a Brix Scale and a Specific Gravity Scale, the scale most homebrewers use.

Why use a Refractometer you ask?
Are you tired of not hitting your desired target gravities? Have you tried to cool a large sample so you could use a hydrometer and see what your gravity is? A refractometer allows you take instant gravity readings, with just one drop, at any point during the boil, or even during the run off of the sparge during an all-grain brew. These 'during the process' readings allow you to add more water or boil longer so you can attain exactly the gravity you desire.

Refractometer Statistics
Our refractometer is hand held with a metal body, flexible eye piece and rubber grip. It features a 0 to 32% Brix scale and from 1.000 to 1.120 on the Specific Gravity Scale with .2% resolution and ATC (Automatic Temperature Compensation). Traditional refractometers without ATC are calibrated to work at 68 degrees Fahrenheit. The ATC function allows you to use the refractometer in an ambient temperature range of 50-86 degrees Fahrenheit (10-30 Celsius.) Because your sample is just one drop, and will quickly adjust to the temperature of the refractometer, the temperature of the sample is irrelevant. Our unit also comes with a manual calibration knob that is secured with a lock nut. To calibrate place one drop of distilled water on the testing platform and adjust to zero if necessary.

Getting Geeky about why the Specific Gravity Scale on our unit is accurate
Some dual scale refractometers feature a linear scale that multiplies brix by 4 to get Specific Gravity. This is okay at lower gravities up to around 1.040 but the higher your starting gravity goes, the less accurate the conversion is. For example, take a Brix reading of 10, multiply by 4, and you get a SG reading of 1.040 - the accurate SG reading is 1.041. Take a Brix reading of 20, multiply by 4, and you get 1.080 - the accurate conversion is 1.084. We worked with our Refractometer manufacturer to create a unit with a non linear conversion and thus this model can be accurately used for Specific Gravity readings.

NOTE - Refractometers will not read correctly if alcohol is present. We have a spreadsheet that can be used to help determine your actual gravity or brix, and this can be found in the "Documents" tab above.

Works great and easy to keep clean
Easy to read with proper lighting. I like the dual scale with both brix and gravity saves me from having to calculate one or the other.

Great Device
Fantastic tool to have. A bit of a learning curve. Didn't know you had to adjust alcohol in fermented wort. Found the tool on BeerSmith to calculate the adjustment. Works like a charm

Beats Hydrometer
Quick gravity readings without taking a big sample. I haven't touch my hydrometer in years.

Wine & Beer
Can't get any better than this. Easy to read, durable, dependable and accurate. I use it in the field and in the shop regularly and check it against other instruments occasionally and do the math. Had it for four seasons now and still ticking. Will buy another when it passes.

works well
works well but wish the instructions mentioned that you cant use it for post fermentation. I probably would not have bought it had I known.

Like It
I really like this dual scale. T'was always a bit of a pain to have to do the conversion.

economy tool that should replace most hydrometer in being kits.
After a few years of owning and using this I've found it's great to use a smaller sampler to find the data you're liking for, but I have also found this to not be very accurate and getting different numbers from same batch even same small sampling.
I'll check with h2o between samples and the water will be accurate. So in the end just take the bad with the good. It's reasonably priced, easy to use, just sometimes it's not very accurate.

Very Handy for All Grain Brewing
This handy tool is great for checking your pre-boil gravity after sparging. It is accurate as long as you read the instructions and calibrate it properly. Re-calibrate from time to time to be safe. The first time I used it (after calibrating) I compared the refractometer reading with a hydrometer reading and they were identical!

I was hesitant buying this as many of the reviews regarded the inaccuracy but I have tested it several times against my hydrometer and it has been +/- no more than .002 every time. This is a MUST HAVE if you are making the step up to all grain.

Side tip, this are great to use when making a starter as well! No more guessing at your ratios.

Good tool for the price
Good price for a dual scale refractometer, holds calibration well and reads accurately. Overall construction is good, and the fitted case is a nice touch for protection. Easy to read with a bright light source, can even take photos of readings with my cell phone camera.
