The 



HI96801 is a rugged, portable digital refractometer for food products designed to report the sugar content of aqueous solutions as % Brix. The HI96801 report the results with an accuracy of ±0.2% Brix. The operation of the meter is simplified with only two buttons: one button is to calibrate with distilled or deionized water and the other to take a measurement. All readings are automatically compensated for temperature variations according to the ICUMSA Methods Book standard and displayed within a 1.5 second response time. The sealed flint glass prism and stainless steel well are easy to clean. Just wipe with a soft cloth in preparation for the next sample.

Details

The HI96801 Digital Sucrose Refractometer converts the refractive index of a food sample to % Brix. This conversion is based on the tables found in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis) that documents the changes in refractive index with temperature for a percent by weight sucrose solution. The HI96801 is ideal for the analysis of fruits, energy drinks, puddings, soy milk, juices, jam, marmalade, honey, soups, jelly, tofu and condiments. The HI96801 is an easy-to-use tool for measuring sugar in food samples in the field or in the lab.

  • Designed for food sugar analysis
  • Temperature Compensation algorithms based on sucrose solution
  • 0 to 85% Brix range with an accuracy of ± 0.2%

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 100g.
    • Note: Solutions above 60% Brix need to be vigorously stirred or shaken and heated in a water bath. Remove solution from bath when sucrose has dissolved. The total quantity can be scaled proportionally for smaller containers but accuracy may be sacrificed.

Example with 25% Brix:
% Brix (g/100g)Sucrose (g)Water (g)Total (g)2525.00075.000100.000

 

refractive index

 

Refractive Index

The HI96801 takes measurements based on a sample’s refractive index. Refractive index is a measurement of how light behaves as it passes through the sample. Depending on the sample’s composition, light will refract and reflect differently. By measuring this activity with a linear image sensor, the sample’s refractive index can be assessed and used to determine its physical properties such as concentration and density. In addition to the linear image sensor, the HI96801 uses an LED light, prism and lens to make measurement possible.

Variations in temperature will affect the density of a solution based on the compound that is present. In digital refractometry the use of temperature compensation is necessary for accurate results. The HI96801 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with the ICUMSA Methods Book Standard for a percent by weight sucrose solution at 20°C.
