There are different types of
refractometers for different tests like:
1.Gem
Tester
Gem
Tester Refractive index is one of most important optical
parameter. Gloss of gem can be
estimated by the parameter.
The
kinds of gem can be precisely determined in accordance with the
measured value of refractive
index
because every kind of gem has its inherent refractive. Besides,
index of double refraction can
be also
measured. Through the parameter you can judge whether a gem is
uniaxial or biaxial
photopositive or photonegative.
The
gemological refractometer is characterized by small volume and
less weight. It is easy to carry.
It is a
popular instrument used in jewelery market.
2.Hand
held Refractometers
The Hand
Held Refractometers are specially designed for measuring the
concentration of many kinds of solution listed as following:
Juices,
Beverages,
Honey,
Salt water, Brine, Cleaning fluid, battery fluid, Antifreeze and
Industrial fluids etc. And they can
also
test for the proportion of the water-soluble solution. They can
be easily used and they are competitive in price. You only need
to
drop
some water on the prism and then make it towards to the
sunlight. Then the reading of the concentration will appear. And
ATC
3.Brix
Refractometers
Developed for working with sugar related liquids (fruit juices,
soft drinks ,
wine), help monitor
and control sugar
concentrations in foods and beverages. Whether users are
checking the “ripeness”
of fruit in the field,
verifying product quality
after
harvesting, or controlling concentrations during processing and
packaging, refractometers provide critical information to ensure
product
quality. But,it is also commonly used for controlling the
concentration of various industrial fluids cutting lubricants
and flux
rinsing
compounds)
3.Salinity Refractometers
designed
for testing the concentration of salt water and brine. Its
triple scale provides a direct reading of the
specific
gravity and concentration
（Parts
per Thousand）of
salt in water and The RHS-10 proves itself invaluable for
agriculture、
food
processing and wildlife management. This instrument is equipped
with Automatic Compensation making it ideal for field use.
