The DRFH series has been discontinued. Please see the RFH Series as possible alternatives or contact our Engineering department.
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
OMEGA™’s 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
including Brix scale,
alcohol, propylene glycol,
protein in serum, salinity,
Baumé scale, industrial
fluids, and specific gravity.
