Refractive Index

The actual measurement of refractive index is simple, quick and provides the operator a standard accepted method for sugar content analysis. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds these instruments measure the refractive index, apply any necessary calculations and display the results in the selected unit. These digital refractometers eliminate the uncertainty associated with mechanical refractometers and are easily portable for measurements in the field.


These five instruments utilize internationally recognized references for unit conversion and temperature compensation and employ methodology recommended in the ICUMSA Methods Book (internationally recognized body for sugar analysis). Temperature (in °C or °F) is displayed simultaneously with the measurement on the large duallevel display along with icons for low power and other helpful messages.

Measures the refractive index in aqueous solutions. Readings can also be displayed with sucrose temperature compensation (nD₂₀) or % Brix.

• 1.3300 to 1.5080
Refractive Index range with ±0.0005 accuracy
• 0 to 85% Brix range with ±0.2% accuracy

Making a Standard % Brix Solution

To make a Brix Solution, follow the procedure below:

• Place container (such as a glass vial or dropper bottle that has a cover) on an analytical balance.
• Tare the balance.
• To make an X % Brix solution, weigh out X grams of high purity sucrose (CAS #: 57-50-1)
directly into the container.
• Add distilled or deionized water to the container so the total weight of the solution is 100 g
