Designed with simplicity in mind, RFM742-M refractometer with Brix, RI scales as standard offer digital automatic technology at a low cost.

  • Overview

    RFM700-M Series refractometers are robust, low-cost, fully automatic instruments that are ideally suited to the food, sugar, and beverage industries but can also be used in many other non-food applications where temperature control is not required, for example, measuring sugar (°Brix) concentrations in the food processing industry.

    Robust 2-decimal 0-100 Brix refractometer for use in factory or lab with automatic temperature compensation. Designed with simplicity in mind, the RFM742-M refractometer with Brix RI scales as standard offers digital automatic technology at a low cost.

    • Alpha-numeric keypad for easy data entry
    • Flat sapphire prism surface for easy cleaning
    • Simple operation for factory environments
    • Selectable read type: Continual, single, intelligent auto-sense
