Refractometers
Here you will find a variety of refractometers for the
measurement of dry substances and different mixtures.
We have different refractometers for ranges of 0-10,
0-18 up to 45-82% brix or degrees Oechsle (°Oe) to
evaluate wines and liquors, as well as refractometers
for the food industry. One of our refractometers, the
DRC-200, is used for analysing urine. We also have
refractometers that can measure the quantity of coolants,
anti-freeze, thickeners, etc. Refractrometers are easy
to use and highly accurate optical devices which are
based on the principles of light refraction by a prism
through a small sample of a substance to get a reading
and is ideal for all types of professionals. Here are
conversions for
refractometer
measuring units. All our refractometers come
with
ATC
except the PCE-SG and include automatic temperature
compensation. If you don't find the temperature

Refractometers for beekeeping, for salt content and for coolants.
Some refractometers come with different unit scales. The visible
line between the blue area and the white area defines the
reading. With Oechsle - Winzer refractometers, you can measure
in ºOe, Brix and Babo.

Refractometers for beekeeping |
If you
wish to determine, with the help of a refractometer,
concentrations in watery solutions that don't appear
in the previous list, including those containing
colourants, this does not pose a problem. You should
only measure a sample once wth a refractometer.
Using the following example, let's say the result
was 12.9% brix. Now we take a dry sample of the same
substance in a drying cabnet or a chemical analysis
in a laboratory. As an example, the result is 8.2%
of the solid matter. Now divide both results and the
factor is 1.57. In this way, we obtain the
correlation between the refractometer and the
laboratory. Now when we measure using only the
refractometer we will only need to divide the
readings by the value 1.57 and we will then see the
value of work. The following link shows a
conversion
table of degrees Brix to potential alcohol
content (% of Vol.) and a summary explanation of the
measurement
process. |

Many of our refractometers indicate the measurement result
in degrees of Brix. Liquid has a level of one Brix (=1% Brix)
when it possesses a minimum density of a solution containing 1g
sucrose to 99g of water; it has
10 Brix (=10% Brix) when its density is equivalent to a
content of 10g
sucrose in 90g of water. Sucrose is used as an indicating
reference for content of sugar. The measurement for a dry
soluable substance in a liquid (and as such we can
approximate the content of sugar, is normally indicated in
degrees Brix (º Brix). Indirectly we establish the value of
the ripeness of fruit.
Some CE commercial standards , for kiwi and melon, stipulate
that fruit require a sufficient degree of ripeness, which
means to say that the standard requires that the fruit have
a certan Brix value. The unit of measurement used by
refractometers takes its name from Adolf F. Brix, a
scientist in the 19th century who, in 1870, developed the
means for determining the content of sugar in liquids. The
CE commerical standard for kiwis, melons and watermelons
clearly establish the measurement value taken by
refractometers to determine the ripeness for harvest.
One
group of refractometers in particular are the Abbe model of
refractometers which are optical devices used to determine
the refraction index of liquids. Considered as complete
refractometers, the principle of measurement is based upon
what is made of the liminted angle of the total reflexion
over a surface limit depending on the index of refraction of
the optical measurement. The structure of the Abbe
refractometer allows for an accurate determination of the
angle limit with a cap of liquid being placed between two
crystal prisms.

We have refractometers
available to take measurements of water and sugar
content in honey. |
We also have refractometers available for measuring
alcohol content in clear liquids that contain no
pigmentation. |
We have refractometers for
the wine industry that can determine the potential
alcohol content of a grape. |
