RFM300-M Refractometers with Temperature Control and Membrane Keypad
Bellingham & Stanley


The RFM300-M brings the RFM300+ refractometer up-to-date with a line of high precision Peltier temperature controlled benchtop refractometers. The RFM300-M is identical in features to the recently launched RFM300-T series in all aspects except for its tactile keypad. Incorporating wide beam optics and one of the flattest prism platforms on the market, RFM300-M series refractometers are capable of measuring non-homogenous samples such as fruit juice with pulp, opaque chemical compounds and emulsions.
  • 4" high definition display with robust push-button keypad for factory use.
  • Flat prism surface for easy-cleaning.
  • Wide beam scan for non-homogenous samples.
  • 3 decimal place Brix precision (6 d.p. RI).
  • RFID user clearance.
  • Supports FDA regulation 21 CFR Part 11.
  • PHR-MEAN Method.
  • USB and Ethernet connectivity.
