Refractometers for Food and Beverage Applications
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.
Automatic Temperature Control
Sample temperature stability is also important. The RFM700-M Series allows the input of a delay time that forces the operator to wait for countdown before reading, ensuring reliable results every time.
Date, time, batch & operator identifiers can be entered via the alphanumeric keypad or in the case of batch numbers, via a barcode reader connected to the instruments USB port. Over 8000 results can be saved for download. The instrument can also be connected to a printer or laboratory PC, with results being output in printed or CSV formats or as a Secure PDF.
Another new feature for the RFM700-M Series is the instruments ability to sense a sample being placed on the prism so that it can make a measurement “hands-free.” Push-button or continuous read functions are also selectable.
