REF-85
REF-85, Portable Refractometer
The REF-85- 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 & 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 REF-85- digital refractometer eliminates the uncertainity associated with
mechanical refractometers and is easily portable for measurements in the field.
The measurement technique & temp.
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 mea-
surement on the large dual level display
along with icons for Low Power and other
helpful message codes.
Key features include:
Dual-level LCD
●
Automatic Temp. Compensation (ATC)
●
Easy setup & storage
