OPERATION MANUAL
RSD Refractometer
INTRODUCTION
Thank you for choosing our refractometer. This is an easy-to-use device, requiring little to no
training. Please read the manual before using to ensure optimal measurement.
The refractometer is designed for fast and accurate determination of fluid concentrations. The
instrument will automatically compensate for temperature fluctuation and can be used for years
of trouble-free service when properly and regularly maintained.
The refractometer represents reading relative to Brix scale. The Brix scale originated in the food
industry and is primarily a unit of measure corresponding to percent of sugar in a sugar and
water solution. The actual Brix value represents the number of grams of cane sugar in a 100
gram cane-sugar solution (percent sugar wt./wt.). This direct reading relationship holds true
only for sucrose solutions. When measuring non-sugar solutions, the Brix scale should be
thought of as an arbitrary scale. To make these arbitrary units of measure meaningful, they
must somehow be correlated to the concentration on the solution you are testing. This is
accomplished by creating a chart of solution concentration relative to the Brix scale. A separate
must be made to each type of solution being tested.
