About the Trade Mark:

Year 2005-ATAGO was established 65 years ago and we have been developing,
manufacturing, and marketing Refractometers based on our in-depth study of optics. This
year we have released our NEW Hand-Held Refractometer series, the

“MASTER” to

support and meet our customer

’s needs. The NEW “MASTER” series is a fitting name to

match its ultimate performance. The trade mark,

“光” is the Japanese Kanji which

means

“light” The decision to use this Kanji as a trade mark for the MASTER series is to

emphasize that this product was designed and manufactured in Japan. With the
multitude of imitation products out in the market today, ATAGO is maintaining our identity
as the master of manufacturing quality instruments. We, ATAGO, would like to be your
business partner and to be the

“light” to continue towards a bright future together.

Efficiently using an analog unit depends on
how easily the measured value can be read.
With extensive research and the utilization
of quality optics, the result is a view of the
m e a s u r e m e n t s c a l e t h a t i s v e r y b r i g h t ,
creating a high contrast to see clearly where
the boundary intersects the memory lines of
the scale.

Reasons to choose the MASTER

The concept of a washable hand-held analog
unit is exceptional. After measuring, you can
clean the refractometer with running water
under a faucet. The new structural-design
of these units allows them to be washed
whenever necessary.

Water Resistant

This new system allows the MASTER series
to have improved accuracy that outperforms
similar units. ATAGO has applied for a patent
on the design of the improved ATC system.
The MASTER series reads more accurately
than any comparable unit on the market.

Automatic Temperature Compensation (ATC)

The MASTER series design has a smooth and
easy-to-clean grip, eliminating the possibility
of food and other samples being trapped,
w h i c c o u l d r e s u l t i n c o n t a m i n a t i o n a n d
bacterial growth.

Hygienic Design

ATAGO has developed a spoon-shaped tip,
which makes applying the sample easy, and
helps the sample spread across the prism on
its own. This makes the instrument even more
user-friendly. (Patent Pending)

Automatic Sample Distribution (ASD)

The MASTER series has passed all water
resistance, dust resistance, and drop tests.
The only replacement part for the MASTER
series is the daylight plate. The instruments
do not utilize consumable parts or materials,
thus keeping the cost for replacement parts
to a minimum.

Durability

ATAGO has built a fi rm reputation for reliability
and quality during its 69 -year history. We are
a strong company that exports to over 154
countries with continued growth expectations.
ISO 9001 certifi ed, along with our integrated
sys tem for pr oducing a nd ma r keting our
products, based on the “Plan-Do-Check-Act”
cycle, is essential to the continued quality and
to the promoting of the ATAGO name.

Reputation for Quality

ATAGO has established a close network of
customers by providing excellent customer

customer treated with respect, but they are
also provided with detailed methods and user-

measurements, based on individual needs.

refraction

When a straw is placed in a glass of water, the straw appears bent. When a straw is placed in a glass
with water containing dissolved sugar, the straw should appear even more bent. This phenomenon is
known as the principle of

light refraction

. Refractometers are measuring instruments which put this

phenomenon of light refraction to practical use. They are based on the principle that as the density of
a substance increases (e.g. when sugar is dissolved in water), its refractive index (how much the straw
appears bent) rises proportionally.

Sugar concentration

Fruit juices, jam and honey contain many elements
but the main ingredient is sugar. Sugar concentration
can be indicated in Brix (%). Brix is a measurement
scale based on sucrose in distilled water. For example,
10 grams of cane sugar in 90 grams of distilled water
equates to a 10 % Brix solution. Since the majority of
dissolved solids in fruit juice are sugar, the Brix scale
is ideal to measure these samples.

Concentration

S o u p s , s t e w s , a n d s a u c e s
contain salts, acids, ex tr acts
as well as sugar. The total of all
these dissolved ingredients in
water is called “Soluble Solids”.
The concentration is generally
indicated in percentage.

Brix

A r ef r ac to mete r me a s u r e s t he co nc e nt r atio n pe r ce nt ag e a n d
displays this as a value of Brix(%). When measuring samples such as
fruit juice or jam, which consist almost entirely of sugar, the Brix(%)
should almost equal the actual sugar concentration. With samples
such as soup or sauce containing many other ingredients, the
Brix(%) is indicating the total concentration percentage. Generally
the measurements obtained are not indicated specifi cally as

SUGAR

CONCENTRATION

or CONCENTRATION , but simply Brix(%) .
