Calibration
All water-based solutions can
make light bend, a process
known as refraction. The rate
at which light bends is in direct
proportion to the solution
concentration. A refractometer
is an instrument that measures
the concentration of an
aqueous solution by
calculating its refractive index.
Refractometers are used
throughout the food,
agriculture, chemical, and
manufacturing industries.
OMEGA DRFH450 Series
handheld digital refractometers
are lightweight, precise optical
instruments that can determine
the refractive index in only
a few drops of solution.
These refractometers are
suitable for a wide range of
measurement applications,
including Brix scale, alcohol,
propylene glycol, protein in
serum, salinity, Baumé
scale, industrial fluids, and
specific gravity.
