GENERAL DESCRIPTION
The HI 96801 Digital Sucrose Refractometer is a rugged portable, water
resistant device that benefits from Hanna’s years of experience as a
manufacturer of analytical instruments.
The HI 96801 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. The HI 96801 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.
