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.
