Digital refractometer - 1.32-1.58 RI ±0.00004 / 0-100 °Brix ±0.03
RFM300+ series refractometers are considered by many leading companies as the ultimate instrument for installation in demanding factory environments as well as for use as a primary quality control tool. Since its original launch in 1992, over 7,500 models have been installed across the globe and following a complete re-design in 2008 and further developments to the hardware since then, the RFM300+ series of refractometers still offers all the original design attributes but with a wider refractive index range, Peltier temperature control and a more versatile software structure. A shallow, easy to clean prism dish houses a single sapphire prism optical system protected by a sample presser that may also be used to instigate a measurement without the need to press the read button. 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.
