Digital Refractometers HI96803
Quantity
The HI96803 is a rugged, portable digital refractometer for food products is designed to report the content of aqueous solutions containing sugar as % glucose by weight (%w/w). The HI96803 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.

Details
The HI96803 portable refractometer converts the refractive index of a food sample to % glucose 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 glucose solution. The HI96803 is ideal for the analysis of fruits, energy drinks, puddings, soy milk, juices, jam, marmalade, honey, soups, jelly, tofu and condiments. The HI96803 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 glucose solution
- 0 to 85% glucose by weight range with an accuracy of ± 0.2%
Making a % Standard Glucose Solution
To make a glucose 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.
- Weigh out X grams of high purity glucose (CAS #: 50-99-7 directly into a beaker
- Add distilled or deionized water to the beaker so the total weight of the solution is 100g.
- Note: Solutions above 20% may need to be vigorously stirred or shaken and heated in a water bath to roughly 40°C (104°F). Remove solution when fructose has dissolved and allow to cool before use.
