Digital Refractometer RFM700-M Series
|
Bellingham & Stanley Digital Refractometer RFM700-M Series with ATC and Keypad
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.
