A Pocket Refractometer is a small handheld device that measures the refractive index of liquids. It works by analyzing the angle of refraction of light that interacts with samples, providing an accurate measurement of the refractive index.

Digital pocket refractometers are ergonomically designed and provide results within two seconds at the touch of a button. Its compact and lightweight construction makes it effortless to carry in your pocket, so you can take measurements anywhere.

These devices are engineered with high-quality components to ensure a long lifespan. They can withstand harsh environments on the go, in the production area, or in a quality control lab. Compared with analog refractometers, digital refractometers provide more reliable results, eliminate operator dependency, and assist in detecting errors.

The handheld digital refractometer line, Refracto, stores up to 1,100 results and connects to EasyDirect PC software for enhanced data viewing.

Using a digital pocket refractometer is simple. 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 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.

The calibration of a digital pocket refractometer is also very simple.
