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.

Better way to read Gravity
Horacio V G on Jul 20, 2019
I'm looking to simplify my gravity readings during the brew process. Using a standard hydrometer can be an issue due to wort temperature. I'm hoping the refractometer will allow me to take simple, fast, and accurate gravity readings pre and post boil.

more accurate beer brewing
Dennis F on May 12, 2021
The scale in the product image shows a Brix value of 20 correlates to 1.077 SG. However, according to the paragraph above, the correct value is about 1.084. MoreBeer says they worked with their manufacturer to create a more accurate, non-linear SG to Brix scale for the refractometer. Is the product image incorrect or am I missing something?
Blake Loyd on Jul 25, 2020
BEST ANSWER: I purchased one in June 2019. I just looked through it and 20 Brix corresponds to 1.083 SG, as it should. My refractometer has always agreed with my hydrometer very well (for unfermented wort).
What is the difference between the mt700 ($59) and this mt708 ($39)?

Dual Scale Refractometer w/ ATC & LED Light
Dual Scale Refractometer w/ ATC & LED Light
BEST ANSWER: CORRECTION: mt700 ($59) does NOT have a light, it has a focus dial which works great for those with glasses. The cheaper mt708 ($39) has the LED light, but my understanding is it does not have a focus dial based on some of the reviewers mentioning they struggle to read the scale with glasses. The mt700 also comes with the dropper and small screwdriver for adjustments.
Does this come with a dropper (eye dropper) for extracting wort?
Stephen Miller on Aug 22, 2019
BEST ANSWER: No, just the refractometer and instructions.

Good product
Even with my poor vision I can read the scales. Easy to read and agrees with my hydrometer (1.050 range). Convenient to use after mashing to see if I hit my OG targets. Will start to use in the vineyard soon as well.

Simplifies readings on brew day
This unit was super easy to calibrate and is amazingly easy to use. It has simplified my brew day as readings don't require thieving nearly as much liquid.

Low Volume Gravity Measurement
Picked this up after trying to use a thief and hydrometer for gravity measurements. This is so much easier, I can imagine using my hydrometer over it ever again. Requires just a few drops to get a measurement, and since it is such a small volume, the temperature of the sample will cool to room temperature very quickly. The dual scale is very easy to read and comes in handy to know both Brix and SG for the OG and to make corrections for EtOH during/after fermentation. Easy to calibrate with a set screw on the unit and a few drops of distilled water.

Great deal on a nice refractometer. Only takes a few drops of wort vs a 1/2 cup or so with a hydrometer. Same reading as with the hydrometer, but much easier and faster.

Works great. Lines are easier to read than my old refractometer. Love the SG scale is independent of the brix one.
