RFM860
Wide Range Refractometer with four decimal place
(RI) resolution and peltier temperature control
The RFM800 series now comprises four standard models that allow the user to select the instrument
that best suits their particular application. Models vary according to measuring range, resolution
and accuracy. All RFM800 models are equipped with standard scales: RI and sugar % (°Brix)
and with sucrose-based automatic temperature compensation. Many other scales are
available from the instrument library or alternatively, users can create user-defined scales
and temperature compensation coefficients from measured data by using free software
available from the Internet.
The latest instrument to be included in the RFM800 range is the RFM860,
launched in January 2005. The instrument incorporates the widest available
refractive index measurement range but in order to meet certain measurement
criteria, the resolution and accuracy of the instrument is to four decimal places,
making it ideal for many industrial applications including chemical, pharmaceutical,
flavours, fragrance and petrochemical.
Other new features, global across the RFM800 range, have been added since the instrument
was launched in 2002. These include ‘Smart’ temperature stability checking, where instrument
temperature and measurement repeatability is compared against pre-set tolerances prior to displaying a result, as well as
‘BeerSmart software’ for alcohol content measurement of beers when used in conjunction with a density reading.
Barcode Readers are also now available, allowing rapid
