  • Automatic refractometers Bellingham and Stanley RFM500 series

    This 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
