Digital Refractometers
& Polarimeters
FOR PRECISE MEASUREMENT OF CONCENTRATION AND PURITY
Precision measurement of concentration and
purity in laboratory or factory environments
What is Refractive Index?
Feature Key
When light passes from one medium
to another, the speed at which the
light travels will change depending on
the parameters of the materials. This
principle can be seen when looking
at a straw in a glass or an
oarsman on the river, as
shown in the diagram.
The ratio or change in the
speed of light is called
refractive index and instruments
that measure this are called
refractometers.

What is Optical Rotation?
When plane-polarised light
passes through an optically
active substance, the plane
of polarisation will rotate by
an amount that is specifically
related to the product through
which it travelled.
As many chemical
compounds display this
chiral characteristic, the
measurement of optical
rotation using a polarimeter
is commonplace within the
sugar, food, chemical and
pharmaceutical manufacturing
industries as a production
control and quality assurance tool.

RFM700 Refractometers
RFM700 series refractometers are robust, low cost, fully
automatic instruments that are ideally suited to the food, sugar
and beverage industries but can also be used in many other
non-food applications where temperature control is not
required.
Commonly, the RFM700-M series refractometers are
supplied to operate in the °Brix scale with results
temperature compensated to 20°C in accordance
with ICUMSA. Additional user scales provide
measurement in different formats such as Refractive
Index (RI) various wine, urine specific gravity &
automotive scales as well as allowing custom scales
to be loaded in accordance with product data.
Inherent to the robust design is a sapphire prism
mounted in an easy-clean stainless steel dish and an outer
casing that is sealed and shaped to withstand sample spillage
and moisture ingress. This, together with the external power
supply and bright 4” high definition full colour display, makes
the RFM700-M ideal for use in busy laboratories or harsh
factory environments. The instrument can also save
and/or print results and be connected to a printer or laboratory
PC, with results being output in standard print, CSV or secure
PDF formats.
Other software features include special AG temperature
compensation that facilitates a SPAN calibration when using
AG calibration fluids, and a time delay before reading, ensuring
reliable results every time.

RFM300 Refractometers
The RFM300 Series of refractometers are the result of a
combination of over 100 years’ experience in design and
manufacturing led by customer needs. With a wide measuring
range and Peltier temperature control of the
flat, easy clean prism, the RFM300 Series
refractometers offer extremely rapid
temperature stabilization of the sample,
allowing readings to be taken quickly
and reliably in any scale including Brix,
Refractive Index (RI) or up to 100 user
defined scales.
Whether a high resolution 7”
touchscreen (RFM300-T) or a more
tactile keypad (RFM300-M) is required,
the graphical user interface with easy
to use menus gives the RFM300 Series
instruments a fresh, modern look
and feel.
A large sampling area on the prism surface
allows measurement of not only homogenous fluids like juices,
sodas, sauces and edible oils, but also difficult to read samples
like fruit pulps and industrial resins.
Intelligent software ensures rapid temperature response to
changes in prism temperature, whilst the SMART temperature
stability check makes sure that the result is displayed only
when the sample is stable. A Methods system allows rapid
configuration of instrument setup and provides limit checks
against stored data as well as product-specific corrections,
such as citric acid content for orange juice or coffee solids daily
offsets. Over 8000 readings may be stored within the instrument
memory and the on-screen menu may be displayed in a number
of different languages.
The instrument is available in two formats, the most popular
being the 3-decimal place Brix RFM340 refractometer, which,
following improvements to the thermodynamic control system,
now has an increased measurement performance between 0-30
°Brix and so reduces potential measurement error in the critical
range covering finished products like the aforementioned
juices and sodas. By improving the performance at the low
end of the scale, users may now trim syrup dilution to the
absolute minimum without the risk of breaching manufacturing
specifications.
SG scales for sucrose are also common to the series. These
scales may be used to express the relative density of pure
sucrose solutions and, when used in conjunction with a product
4
offset from within the Methods system, can express finished
beverages as an equivalent SG. By doing so, contract packers
of beverage products may now use a refractometer in situations
where density °Brix or SG is dictated as the method of analysis,
whilst retaining all the measurement advantages held by a
refractometer. A dual display function allows original Brix or RI
to be displayed alongside the equivalent sucrose SG result.
Other new features now standard on the RFM300 Series include
RFID User Clearance, electronic signatures and audit trails that
facilitate use in an FDA regulated environment (21 CFR part 11)
as well as enhanced functionality via the new USB interfaces
such as Back-up & Clone and Print to Secure PDF.

RFM900-T Refractometers
Featuring a new touchscreen display and wide measuring
range up to 1.70 RI and capable of measuring to six
decimal places, the RFM900-T Series refractometers are
ideally suited for use in the chemical, petrochemical,
pharmaceutical, flavours and fragrance industries
as well as for academic research. The RFM900-T
series of refractometers combine the latest optoelectronic principles with durability and ease of
use. RFM900-T refractometers feature RFID (Radio
Frequency Identification) that allows users to
identify themselves by simply swiping a tag
across the top of the instrument to enable
measurement and, in certain cases, access to
the configuration menu.

RFM Flow Refractometers
Micro Flowcell
Micro flowcells are used to transfer volatile or limited volume
low viscosity liquids as part of a single or multiple instrument
analysis, often incorporating an autosampler and pump within the
beverage, brewing, flavours, fragrance or essential oil industries.
Macro Flowcell
Macro flowcells are used where sample viscosity limits the use
of micro-flowcells or for connection to a pilot plant or smallbatch process line, where a normal process refractometer may
not be suitable.
Funnel Flowcell
Where larger volumes of sample are available, a funnel flowcell
may be used. These negate the need to clean the instrument
prism between sample measurements, providing a rapid
sample turnaround, such as in Tare Houses of grape growers
co-operatives and sugar mill receiving stations.
RFM990 Flow Refractometer
The RFM990-Flow is a wide range Peltier

Pro-Juice Refractometer
For many years, beverage manufacturers
have adopted digital refractometers as
their primary instrument for measuring
the final dilution ratio (°Brix) of reconstituted fruit juice not only to
assure product quality but also in
an attempt to reduce losses by
tightly controlling concentrate
yields. For most fruit types this
has been successful but for one of
the most commonly produced juices, the
high accuracy measurement achieved by latest
technology digital refractometers has unmasked an erratic
behaviour within an orange juice sample that prevents
tighter dilution control. This negates any opportunity of cost
reduction by way of lowering target values without the risk of
compromising minimum specifications defined by regulation.
The Pro-Juice refractometer has been specifically developed
to overcome the erratic behaviour of orange juice by focussing
on the practical handling of the sample prior to high accuracy
measurement in order to achieve a measurement accuracy
of 0.01 °Brix for sucrose solutions. More importantly, a
reproducibility of 0.02 °Brix between orange juice samples,
regardless of temperature deviation or operator skill level. The
Pro-Juice refractometer has two modes of operation allowing
standard juices to be measured in a conventional manner.

ADP400 Polarimeters
ADP400 Series polarimeters now feature a full colour, 4”
(10 cm) high definition display. Measurement may be
expressed as angular degrees (°A), sugar (ISS) or user
programmable scales, with standard Methods facilitating
display of invert sugar, inversion (A-B) or, when applying
other factors such as tube length and concentration, Specific
Rotation (or concentration when entering specific rotation).
The ADP400 Series offers both continuous and ‘single-shot’
reading modes, the latter being ideal for pharmaceutical
applications where a discrete value is required without
interpretation by an operator.
The PHR-MEAN Method, integral to both ADP400 Series
polarimeters, allows a number of different readings to be
taken from a batch of samples and the statistical report,
showing the average, high and low results together with
standard deviation can then be printed or stored to file.
The expanded memory ensures that over 8000
measurements and recorded logs of instrument
configuration can be saved and viewed or output to LIMS.
Calibration and configuration can be password protected,
accessible by keypad entry or, for convenience, using a
fully configurable RFID tag. This, together with the audit
trail, facilitates operation in environments conforming to
FDA regulation 21 CFR Part 11 or GLP. ADP400 Series
polarimeters are also ideal for use within laboratories where
compliance with Pharmacopoeia is required.
The ADP400 Series polarimeters incorporate a number of
industry standard interfaces making it easy to connect to
peripheral devices including barcode readers, printers and
USB memory sticks for external storage. With the addition
of a USB memory stick operators can output results to a
secure PDF using the “Print to Secure PDF.” The
USB port can also be used to accept RS232
via an available adaptor.
There are two instruments in the
ADP400 Series.

ADP600 Polarimeters
Available as single, dual and multiple
wavelength derivatives not only covering
the visible spectrum, the new ADP600
Series of Peltier temperature
controlled polarimeters are capable
of measuring optical rotation to four
decimal places in the highly sensitive
ultra-violet region. This capability
makes the instrument particularly
suited for use by scientists wishing
to measure chiral compounds and other
optically active substances in the chemical,
pharmaceutical and food sectors as well as for use in
academic research.
• Single, dual & multiple
wavelength models
• Four decimal place
resolution
• Peltier temperature
controlled
• High definition 7.4“
touch-screen display
Peltier technology is intelligently applied to the sample
chamber of the new polarimeters so that measurement
can be accurately made without the need of an external
waterbath. The ADP600 Series Polarimeters have two preset
operating temperatures being 20 and 25 °C in accordance
with European and United States Pharmacopoeia
respectively and other user temperatures between 20 and
30°C may be configured via the instrument user interface. ADP600 Series Polarimeters accept standard glass or

special low volume leur taper polarimeter tubes facilitating
measurement across optical path lengths between 5 and
200m with tube diameters from 3 to 8mm being readable. Optional lids may be easily be fitted to the ADP600 Series
Polarimeters, facilitating sample tube entry and exit.
Integral to operational simplicity is the full colour, high
definition, touch-screen graphical user interface. A menu
structure featuring a METHODS system makes for onetouch calibration and instrument configuration; especially
where the specific rotation of a number of samples is being
analysed over a wide range of concentrations, path lengths,
temperatures and wavelengths. A “Mean Method” is also
available, allowing a number of readings to be taken from
a production batch with the mean being calculated and
recorded once the experiment has been completed.
ADP600 Series Polarimeters have an extensive interfacing
capability. Four USB ports provide excellent connectivity
to, for example, convenient remote keyboards, printers,
barcode readers and LIMS or PC, whilst the Ethernet
connection may be used for networking as well as remote
diagnostics or certification. The ADP600 Series on-board
RFID reader may be used to identify users as well as sample
tube lengths for recording and in particular, calculation of
Specific Rotation.
Additionally the ADP600 Series Polarimeters feature a
secure “print to PDF” function that may be configured to
operate in secure environments in accordance with FDA
regulation 21 CFR Part 11 and importantly, the ADP600
Series polarimeters meet all of the requirements, including
wavelength directives of British, United States, European
and Japanese Pharmacopoeia.

Saccharimeter
• OD indicator
A Saccharimeter is a polarimeter that has been configured to
display the optical rotation in the International Sugar Scale
(ISS – °Z) for operation in the sugar processing industry as
defined by the International Commission for Uniform
Methods of Sugar Analysis (ICUMSA).
Two single wavelength Saccharimeters
are available from Bellingham + Stanley,
differentiated only by the frequency of the
low maintenance LED light source used as
part of the analysis. Latest specification optoelectronics allows measurement of samples with
low transmittance even at sodium wavelength;
however, for applications where the use of lead
acetate is prohibited, the near infrared ADS480
Saccharimeter and Celite® filtrate offers supreme
performance. Commonly, operation is made easy by way of
four graphically presented push button keys and the continuous
reading mode that updates the bright LED display, gives the
user total confidence in the instrument’s performance. A single
temperature sensor provides the measurement for sugar
compensation, whilst quartz compensation facilitates accurate
verification and calibration using a Quartz Control Plate.
PC software is included with all Saccharimeter packages,
providing simultaneous measurement of Brix by refractometer
to calculate PURITY. A robust touch sensitive LCD screen is
available as an optional extra for use with any PC1.
A number of different flow packages are available making the
ADS Saccharimeter ideal for use in any busy Tare House or
refinery laboratory.
