RFM 800    Automatic Refractometer
All RFM800 models are equipped with standard scales: RI and sugar % (°Brix) and with sucrose-based automatic temperature compensation. Many other scales are available and can be provided as optional additions to the standard software. Alternatively, users can create user-defined scales and temperature compensation coefficients from measured data.
