Digital Refractometer for % Invert Sugar by Weight Analysis
$239.99Thank you for your interest in our products. A representative will contact you within the next business day.
The HI96804 Digital Invert Sugar Refractometer converts the refractive index of a food sample to % invert sugar 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 invert sugar solution. The HI96804 is ideal for the analysis of invert sugar produced from honey, jam, or manufactured from the splitting of sucrose compound. The HI96804 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 invert sugar solution
- 0 to 85% invert sugar by weight range with an accuracy of ± 0.2%
Refractive Index
The HI96804 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 HI96804 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 HI96804 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 invert sugar solution.
