Digital Refractometers for Difficult Samples

RFM300-M Series refractometers can measure non-homogenous samples such as fruit juice with pulp, opaque chemical compounds and emulsions that are normally difficult to read with optical refractometers or refractometers that do not address the need to measure “difficult samples.”

Created for users looking for a simple yet fully functional instrument, this is a series of digital refractometers with up to 3-decimal / 0-100 Brix (1.58 RI) and Peltier control. Perfect for measurement and control in demanding food, beverage, chemical and industrial applications.

• • Flat prism surface for easy-cleaning
  • Wide beam scan for non-homogenous samples
  • Peltier temperature control
  • Alpha-numeric keypad for easy data entry
  • Three decimal place Brix precision* (6 d.p. RI)
  • Choice of two models with varying precision

The instrument’s case is ergonomically designed so that any spills are dealt with by the sloping shape of the case or by the PEEK spill barrier that surrounds the shallow, easy-clean stainless steel prism dish.

Available in two different models 

The RFM300-M Series is available in three different models: RFM330-M and RFM340-M. Each model features the same robust construction and easy-to-use software but vary in spec to suit your requirements. Please see the specifications sheet for more details. 

With a durable membrane made from chemical and scratch resistant polyester, the RFM300-M offers a more tactile approach, allowing users to navigate menus at the touch of a button.

The large, clear buttons and 4” high resolution screen help facilitate operation in factory environments, and combined with our latest GUI, help the operator quickly manoeuvre through the menus. On-screen prompts support simple operation such as Method loading, calibration and routine maintenance guiding even the newest member of your staff.

RFID swipe technology comes as standard, providing clearance and a log of operator and configuration functions; especially useful when being used in FDA regulated environments operating in accordance with 21 CFR Part 11, or where good practice is adopted, e.g. as part of HACCP.

Measurements with the RFM300-M are made through a familiar measuring mode or by way of a simple Methods system with one-touch configuration of scale, temperature and data storage, with up to 8000 results being saved alongside pre-set limits that can be used as an audit tool Methods may be user-defined or selected from the on-board library. As an example, the ‘Coffee Solids’ Method allows for coffee type and daily offsets to be inputted, so that the %TS achieved using the refractometer in the factory match the results of the laboratory tests used to configure the freeze-drying process, producing instant coffee powder.
