GENERAL DESCRIPTION

The HI 96804 Digital Invert Sugar Refractometer is a rugged portable, water resistant device that
benefits from Hanna’s years of experience as a manufacturer of analytical instruments.
The HI 96804 is an optical instrument that employs the measurement of refractive index to
determine the % Invert 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 % by weight concentration

units. The HI 96804 digital refractometer eliminates the uncertainity associated with mechanical
refractometers and is easily portable for measurements in the field.
The measurement technique and temperature compensation employ methodology recommended in
the ICUMSA Methods Book (Internationally recognized body for 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.
