Pocket refractometers determine the angle of refraction of light beams that come into contact with samples. Our digital pocket refractometers are ergonomically designed and provide results within two seconds at the touch of a button. Their compact and lightweight design makes them easy to carry in your pocket and take measurements anywhere. Speed up your workflow while improving results repeatability and reducing operator errors!
Our digital pocket refractometers master measurements of a wide range of applications and samples, including Brix, sugar content, refractive index and the concentration of highly volatile, dark, pasty or solid samples.
Engineered with high-quality components to ensure a long lifespan, our pocket refractometers can withstand harsh environments, whether in the lab, on the factory floor, or on the go!
Compared with analog refractometers, digital refractometers provide more reliable results, eliminate operator dependency, and assist in detecting errors.
We support and service your measurement equipment through its entire life-cycle, from installation to preventive maintenance and calibration to equipment repair.
Using a digital pocket refractometer is as simple as ever. Almost anyone can use one by following these three simple steps.
Firstly, make sure the prism is clean. Secondly, add a few drops of sample to the prism—approximately 0.3 ml—ensuring it is well covered. Finally, press the button to begin measuring. You'll receive the results in just two seconds.
All our pocket refractometers deliver results that are automatically temperature compensated and converted into up to three of the 10 integrated sugar-related scales, including Brix, Oechsle, °Baumé, and many more. You can easily toggle through these on the device until you find the number that represents your desired scale.
The calibration of a digital pocket refractometer is very simple. In this video, you will find out how to calibrate and verify a METTLER TOLEDO MyBrix pocket refractometer quickly and easily. All you need to get started is your MyBrix refractometer, a small amount of pure water, and some lint-free tissue paper.
Additionally, you will learn how to get reliable results and perform trustworthy analyses.

Due to their portability, high accuracy, and ease of use, digital pocket refractometers are used across several industries to measure the refractive index of many different substances.
In the food and beverage industry, for example, pocket refractometers are widely employed in production and quality control applications to determine the sugar content (Brix) of fruit juices, carbonated beverages, beer, honey, jams, confectionaries, and much more. To determine the optimal harvesting time, winemakers also rely on pocket refractometers to measure the Oechsle of grape must in vineyards. While it is not as common, you may also find them being used when brewing coffee to measure the TDS (Total Dissolved Solids)—which is a good indicator of how well the coffee is extracted.
In the chemical industry, pocket refractometers are typically used to verify the concentration value of acids, bases, or the presence of organic solvents in inorganic salt (% w/w or v/v). Meanwhile, in the pharmaceutical industry, a they are employed to control the purity and concentration of raw materials, semi-finished products, and end products during manufacturing.
