The HI96801 Digital Sucrose Refractometer is a rugged portable, water
resistant device that benefits from Hanna Instruments’ years of experience
as a manufacturer of analytical instruments.
The HI96801 is an optical instrument that employs the measurement of
refractive index to determine the % Brix of sugar in aqueous solutions. The
method is both simple and quick. Samples are measured after a simple user
calibration with deionized or distilled water. Within seconds the instrument
measures the refractive index of the sample and converts it to % Brix
concentration units.

logy recommended in the ICUMSA Methods Book (International Commission
for Uniform Methods of Sugar Analysis).
Temperature (in °C or °F) is displayed simultaneously with the measurement
on the large dual level display along with icons for Low Power and other
helpful message codes.
Key features include:
• Dual‑level LCD
• Automatic Temperature Compensation (ATC)
• Easy setup and storage
• Battery operation with Low Power indicator (BEPS)
• Automatically turns off after 3 minutes of non‑use.
