protected by a sample presser that may also be used to instigate a

measurement without the need to press the read button. A large sampling area

on the prism surface allows measurement of not only homogenous fluids like

edible and mineral oils but also difficult to read samples like fruit pulps and

industrial resins.

The instrument is available in two formats, the most popular being the 2-decimal

place RFM340+. Intelligent software ensures rapid temperature response to

change in prism temperature, whilst the SMART temperature stability check

makes sure that the result is displayed only when the sample is stable. A

methods system allows rapid configuration of instrument setup and provides

limit checks against stored data as well as product specific offsets and acid

corrections. Over 700 readings may be stored within the instrument memory

and the on-screen menu may be displayed in a number of different languages.

Designed with the most vigorous environments in mind, the RFM300+ can be

fitted with optional extras that allow use in wet and humid factory environments.
