Bellingham + Stanley offer one of the largest choices of digital refractometers in the World today. All refractometers are made to the highest standard and with 95-years of experience, are directly supported by a team of experts and by a global network of fully trained distributors. If you are unsure on which refractometer to choose, please contact Bellingham + Stanley.
Designed with ultimate simplicity in mind, RFM700 refractometers offer digital automatic technology at low cost. Latest models feature more scale and temperature compensation options than their predecessors, enabling the instrument to be used not only in the traditional food, sugar, and beverage applications but also some industrial applications.
RFM700 refractometers are particularly suited to wine applications, as industry standard scales such as Baume, Oechsle, and Probable Alcohol (A.P.) can easily be downloaded from this Internet site. As well as wines scales, a new ‘Fuel System Icing Inhibitor’ scale that conforms to ASTM D 5006 can be loaded as well as refractive index (RI).
Physical benefits of the RFM700 include a flat ‘easy clean’ sapphire prism and a ‘no-presser design’ offers rapid cleaning once a measurement has been taken. A programmable measurement delay is also offered.
The RFM300+ series of refractometers is the result of a combination of excellence in design and manufacture dictated by customer needs. Offering a wide measuring range, temperature control of the flat ‘easy clean’ sapphire prism is achieved by Peltier device, eliminating the need for a waterbath whilst offering extremely rapid temperature stabilization of the sample.
A powerful onboard microprocessor facilitates readout in a number of different scales including RI, °Brix, HFCS etc. and the simple to use secure menu structure can be displayed in a number of different languages. A methods system enables simple operation by any user not matter what skill level; especially for applications where the reading is required to be offset so that results equal an alternative measurement type (oven dried, density etc.) or where a correction is applied such as for citric acid in orange juice.The RFM300+ series of instruments is most suited for use in harsh factory environments in all manner of applications.
The Pro-Juice refractometer has been developed to overcome the widely recognized erratic behavior of orange juice experienced by manufacturers during the reconstitution phase of production. Clever software combined with newly applied sample handling and conditioning techniques are combined within the Pro-Juice to provide unrivalled measurement reproducibility to allow control tolerances to be set closer to the lower tolerance without risk of compromise and in so doing provides an opportunity to improve company profits by increasing concentrate yield.
The RFM900 series of Peltier temperature controlled refractometers comprises two standard models for single application measurement and a flow type instrument. All models cover a measuring range between 1.30 and 1.70 RI such as is the requirement of the pharmaceutical, chemical, petrochemical, aroma, flavour and fragrance industries.
Features include a unique RFID tag identifier that allows rapid identification of users and provides access control to the configuration menu. The instrument conforms to US, European and UK Pharmacopoeia and can be formatted to control data in accordance with FDA regulation 21 CFR Part 11, making it ideally suited for use in restricted areas such as in the pharmaceutical industry.
The RFM960 and RFM970 conforms to petroleum test method ‘ASTM 1218’ for single wavelength measurement and features special software to calculate carbon type composition of mineral insulating oils in accordance with ASTM d 2140 and for aqueous urea solution analysis in accordance with ISO22241, the RFM990-AUS32 provides absolute conformity.The RFM990 flow model is specifically available as a high accuracy version only that may be fitted with one of a number of flow cell variants allowing connection to automated systems such as those found in the beverage, sugar and flavours industries in amongst others.
In January 2008, the RFM800 series of refractometers has been deleted from our range and is replaced by the RFM900 series.
The RFM340refractometer has been deleted. Please refer to other models within our range.
The RFM311 refractometer has been deleted. Please refer to other models within our range of refractometers.
The Abbe Refractometer derives its name from the 19th
Century physicist Ernst Abbe (1840-1905). Abbe designed an instrument for
measuring the dispersion of light and this became the precursor for the so-called ‘Abbe
Bellingham + Stanley offer a number of Abbe refractometers and a choice can be made in accordance with the measurement requirement and budget availability.
The Abbe 5 offers direct refractive index and Brix readings at a low price and is ideal for academia as well as for general measurement within industry.
Abbe 60 refractometers are manufactured to extremely high standards and come in a variety of scale ranges to suit particular application requirements.
The Abbe 60/95 offers high-resolution readings within the Brix scale (better than ±0.2 Brix) and is used for the measurement of viscous corn syrups and sugars, whilst the Abbe 60/DR offers high refractive index measurement to 1.74 to 4-decimal places.
High accuracy, multiple wavelength versions (Abbe 60/LR and Abbe 60/ED) cover a refractive index range from 1.20 to 1.74 RI and require the use of ‘spectral lamp outfits’. As such, the instruments may also be used for measurements of dispersion over the visible spectrum and can provide results to five decimal places – the highest accuracy available with this type of instrumentation. The Abbe 60ED conforms to test measurement ASTM 1218.
The E-Line Gemological refractometer is a low cost, lightweight measuring instrument used exclusively by jewellers and traders of gemstones.
All Abbe refractometers are particularly suited to the measurement of solids and semi-solids such as thin film polymers, rubber, glass and fibre optics as well as liquid samples.
All instruments* feature a temperature control facility by way of waterbath connection and temperature measurement is made by integral sensor and displayed digitally (LCD).
‘Freeware’ for converting results to other scales and for calculating dispersion is available from this site.
