REFRACTOMETERSRefractometer ABBE60 Standard model Bellingham & Stanley
For the examination of oils, fats, optical glass, sugar solutions etc. The refractive index of substances between 1.300 and 1.700 is read directly to 0.001 and can be estimated to 0 0002 from the enclosed glass scale. An additional engraved glass scale, calibrated 0 to 95 x 0 5% Sugar, is provided for estimation of soluble solids in sugar solutions and fruit pulp etc. A sample of approximately 0.5ml is required. With protected thermometer, range 0 to 75C, horizontal prism surface, water jackets and dust cover. For illumination by transmitted or reflected artificial light. With scale illuminator comprising 4V lamp, transformer, ON/OFF switch and mains connector.

Automatic Refractometers Bellingham & Stanley
Fully automatic digital temperature compensated refractometers which offer not only objective results but a wide choice of scales and available as the standard model RFM90 or as the high accuracy model RFM91. Both versions are fitted with a prism of synthetic sapphire and the sample plate is made from 316 stainless steel conforming to all current food processing, health and safety regulations. Scale display is chosen by push button and the machines are factory calibrated and are ready for use.
The RFM91 offers the facility to enter a user-defined scale to give a direct readout for particular products. Typical applications are teas, coffees, special sugars, vegetable oils, etc. The units are very robust, waterproof and are suitable for factory or laboratory use. The model RFM91 is provided with an RS232-V24 output for a printer or computer interfacing. Refractometers are supplied complete with sample press, test piece kit, spare bulb alignment cone desiccator element, screwdriver, 50 disposable pipettes, plastic cover and operating instructions.

Automatic refractometers Bellingham and Stanley RFM500 seriesThis refractometer system has been designed to completely fulfil laboratory refractometric requirements. Customised data handling provides storage of results against specific files with times, dates and reference codes and also carries out the repetitive calculations which are so often required. The basic instrumentation comprises a refractometer sensor head and a control module. The moisture sealed sensor head incorporates an easily cleaned sapphire prism, sample press with water circulation, temperature sensor and connection for a flow cell with the prism either horizontal or vertical.The control module provides readout of any of the ten availale scales on a large display and a small help screen shows current status and labels the four soft keys which allow access to the data handling and calculation menus. A Centronics port allows connection to a printer or LIMS system and two RS232 bidirectional interfaces are also provided. A parallel control port can provide switching of pumps, valves or autosamplers, providing total control within a system Specification
