Technical Specification

Digital Refractometer RFM300-M Series with Peltier Temperature Control and Keypad

RFM300-M Series digital refractometer with 2-decimal / 0-100 Brix (1.58 RI) scales and Peltier control. Perfect for measurement and control in demanding food, beverage, chemical and industrial applications.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.
