Description
Technical Specification

RFM300-T digital refractometer with 2-decimal place / 0-100 Brix (1.58 RI) touchscreen input and Peltier temperature control.

 

Inherent to the design is the high definition, capacitive touch-screen display that not only facilitates operation in factory environments, even when operated whilst wearing gloves, but also serves as the centrepiece for the software. Combined, the touchscreen and GUI help the operator quickly manoeuvre through the user and configuration menus. On-screen graphical prompts support simple operations such as method loading, calibration and routine maintenance.
