A digital handheld refractometer is an instrument that automatically measures the refractive index (or Brix) of a sample by measuring the total reflection. We offer models that are ergonomically designed and provide instant, temperature-compensated results at the touch of a button. Eliminate operator dependency, reduce human error, and improve repeatability with our digital handheld refractometers.
Our refractometers master a wide variety of applications, including refractive index, Brix, and other sugar content or concentrations.
Engineered with high-quality components to ensure a long lifespan, our digital handheld refractometers 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.
We support and service your measurement equipment through its entire life-cycle, from installation to preventive maintenance and calibration to equipment repair.
There are both manual and digital types of handheld refractometers.
For manual types, the Abbe optical refractometer is the most common. It is an optical device and to perform a measurement, you place the sample on a prism. In general, manual handheld refractometers are limited in their ability to measure a variety of samples, so it is necessary to have several portable refractometers to cover various sample types. Furthermore, they are highly operator dependent and more difficult to adjust. These factors can compromise overall accuracy and repeatability.
Digital handheld refractometers, on the other hand, automatically measure samples using a high-resolution optical sensor, which delivers remarkably accurate results. Due to their simplicity and operator independence, they provide greater repeatability and ease of use.
Several industries benefit from the portability and ease of use of a digital handheld refractometer.
In the food and beverage industry, for example, a digital handheld refractometer can be used to measure the sugar content (Brix) of fruit juices and concentrates, carbonated beverages, jams, confectionaries, and much more. As part of the winemaking process, winemakers also use a digital handheld refractometer to measure the Oechsle of grape must in the lab and on the field.
In the chemical industry, a digital handheld refractometer is used to verify the concentration value of acids, bases, or the presence of organic solvents in inorganic salt (% w/w or v/v). While in the pharmaceutical industry, it is typically used for controlling the purity and concentration of raw materials, semi-finished products, and end products.
These are some of the most common applications of digital handheld refractometers, but you can also find them being used in hospitals and pharmacies; during fragrance, aroma, and essential oil manufacturing; in educational centers; and also for a wide variety of applications in the aviation, automotive, and technology industries.
