Digital refractometer
Peltier, 0 - 100°Brix, 1.32 - 1.58 RI, 0 - 70°C | RFM340+
Bellingham + Stanley
RFM300+ refractometers encompass attributes of their predecessors and also offer a wider refractive index range and Peltier temperature control. A shallow, easy to clean prism dish houses a new, single sapphire prism optical system 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.
In 2009, the RFM300+ series has been upgraded to incorporate the new ‘blue screen display’ with enhanced user software to provide an improved user experience. Optional software is also available at point of order to allow use in an environment controlled by FDA regulation 21 CFR Part 11.
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.
