Portable refractometer HI96802 digital

The HI96802 is a rugged, portable digital refractometer for food products is designed to report the content of aqueous solutions containing sugar as % fructose by weight (%w/w). The HI96802 report the results with an accuracy of ±0.2%. 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 with 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. 

The HI96802 Digital Fructose Refractometer converts the refractive index of a food sample to % fructose by weight. 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 fructose solution. The HI96802 is ideal for the analysis of fruits, energy drinks, puddings, soy milk, juices, jam, marmalade, honey, soups, jelly, tofu and condiments. The HI96802 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 fructose solution
• 0 to 85% fructose by weight range with an accuracy of ± 0.2%

Refractive Index

The HI96802 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 HI96802 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 HI96802 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with the ICUMSA Methods Book for a percent by weight fructose solution.
