Only refractometer we know of that has alcohol correction built in. Gives an accurate reading during fermentation when an original reading is taken
Only requires the smallest of samples
Dual purpose: Can be used in the field to measure sugar content of grapes
Costs less than the Anton Paar EasyDens. EasyDens gives accurate readings at any point during fermentation without the need for an original reading.
Our Take: The SmartRef is a very smart digital refractometer. Unlike other refractometers on the market, it will automatically correct for alcohol during fermentation (currently only in beer) and give you an accurate reading. In order for the SmartRef to make the required adjustments for alcohol, it is required that you take an original reading before fermentation. This is a key difference from the Anton Paar EasyDens. With the EasyDens you can take a reading at any point during fermentation without the need of an original reading. Does that feature make the EasyDens worth the extra money? That is up to you of course, but sometimes in brewing we forget to take an initial reading on brew day.
When used together the SmartRef and EasyDens allow for some very unique measurements like the ability to know the original gravity of a beer even without an original reading. To learn more about using these meters together, click here.

The SmartRef Digital Refractometer by Anton Paar is a portable smart pocket device suitable for a wide range of requirements. The SmartGuide+, as a feature in the mobile app, automatically checks any errors of ambient light, impurity, and sample behavior during measurement for you. The device offers more than 15 different measurement units with automatic temperature compensation. Depending on your need, SmartRef enables you to measure the extract content of your beer, the sugar content in wine, the sweetness of fruits and vegetables, the moisture of honey, the salt content of your aquarium or pool, and much more.
Smart Technology for Consistent Results
The SmartRef portable refractometer is used in combination with a free mobile app for Android and iOS via Bluetooth Low Energy and enables intelligent handling of the measurement results.
The app permits easy storage, visualization, management, and sharing of measurement data.
SmartGuide+ detects and helps eliminate measurement problems through high ambient light detection, continuous checking of prism and sample condition, and more.
In addition to the quick measurement mode, measurements in continuous mode allow a more detailed understanding of the samples’ properties.
Over-the-air updates keep your digital refractometer up-to-date with the latest features.
SmartRef Measurement Details
The SmartRef refractometer measures the refractive index of fluids. This allows retrieval of relevant sample properties in a wide variety of applications.
Fast temperature stabilization and automatic temperature compensation for measurement results make additional calculations and correction tables obsolete.
The unit has an IP66 rating and an easy-to-clean stainless steel sample well.
SmartRef supports a one-point zero adjustment with distilled water and requires only a few drops of sample (0.4 mL).
SmartRef displays results in under two seconds and has a measurement range of 0 °Brix to 85 °Brix with an accuracy of 0.2 °Brix.
High Variety of Measurement Applications
Brix refractometer: For wine, juice, honey, sauces, jams, fruits, vegetables, and maple syrup. The SmartRef measures the sugar content in °Brix, °Babo, °Baumé, °KMW, and °Oechsle.
Salinity refractometer: SmartRef determines the salt content in your saltwater aquarium and pool in salinity specific gravity (SG 20/20), practical salinity units (PSU), and salinity in parts per thousand (ppt).
Beer refractometer: SmartRef shows the extract content of wort in °Plato.
As a smart device, SmartRef offers a constant expansion of measurement units. All available scales, such as specific gravity, are provided within the app.

I watched all of the videos and the speed and accuracy of this device is mind blowing. The smartref opens a lot of doors from beer, to meed, to fruited beer, to checking your glycol concentration on your glycol chiller, or more... they have multiple apps depending on the use and still curious to try some of the other features. It takes about two seconds to give you a number and a temp. Heartily recommend this bad boy
This unit is nice because it uses a small sample size and it is easy to clean. My friend has an EasyDens and the measurements for OG are the same. To get an FG reading you have to use the software in the app. The software will calculate the FG. You can manually enter an OG also then select a Measurement for FG. Key is you have to use the software so it calculates. The calculation provided the same FG measurement as on the Easy Dens. This took me a little while to figure out.
