Functions:
A refractometer is an instrument that measures
the concentration of an aqueous solution by measuring its refractive index.
All water-based solutions can make light bend. The bending of light increases
at a rate proportional to the increasing solution concentration. The hand held
refractometer is a precise optical instrument. Its characteristics are small,
light, take only a few drops of solution to use and is very user friendly.
Refractometers are used throughout the food, agriculture, chemical and
manufacturing industries. Our analog and digital refractometers are among the
finest optical instruments in the world. We offer a full line of
refractometers that are suitable for all applications: Brix, Alcohol,
Propylene Glycol, Protein in serum, Salinity, Baume, Specific Gravity,
Industrial Fluids, Refractive Index (nD), along with many other scales which
provide the user with limitless flexibility.
Brix can be approximately converted
to specific gravity (SG) by a simple equation: SG = 1 +(0.004 x Brix)
Most people just remember the multiply by four rule. Take the Brix reading,
multiply by 4 and this will give you specific gravity in ăgravity points.ä For
example, if you read 11 Brix, multiplying that by 4 yields 44, which
corresponds to a specific gravity of 1.044.
A slightly more accurate conversion formula is:
SG = 1.000019 + [0.003865613(Brix) + 0.00001296425(Brix) +
0.00000005701128(Brix)] Using this formula, a Brix reading of 11 yields a
specific gravity of 1.043.
