How Refractive Index Technology Works
The HI96802 measures fructose content by analyzing how light refracts through your sample. Using a yellow LED light source, precision prism, and linear image sensor, the instrument determines the refractive index and converts it to % fructose by weight according to ICUMSA Methods Book standards for fructose solutions. The built-in temperature sensor ensures all readings are automatically compensated for temperature variations, delivering consistent, reliable results.

Preparing Standard Fructose Solutions for Calibration Verification
Procedure:
- Place a clean container on an analytical balance and tare to zero
- Weigh the required amount of high-purity fructose (CAS #: 57-48-7)
- Add distilled or deionized water to reach 100g total weight
- For solutions above 65%, stir vigorously and heat to ~40°C (104°F) until dissolved, then cool before use
