Digital refractometer
Three decimal place Brix precision digital refractometer with peltier temperature control. Featuring wide beam optics and a new 7” touch-screen user interface, the RFM300-T Series is ideally suited for use in demanding applications within the food, beverage, chemical and industrial industries.
A large sampling area on the prism surface allows measurement of not only homogenous fluids like juices, sodas, sauces and edible oils, but also difficult to read samples like fruit pulps and industrial resins.
The instrument is available in two formats, the most popular being the 3-decimal place Brix RFM340 refractometer, which, following improvements to the thermodynamic control system, now has an increased measurement performance between 0-30 °Brix and so reduces potential measurement error in the critical range covering finished products like the aforementioned juices and sodas. By improving the performance at the low end of the scale, users may now trim syrup dilution to the absolute minimum without the risk of breaching manufacturing specifications.
