Digital refractometer, PCE-DRB 2, PCE Instruments

PCE-DRB 2 is a handheld digital refractometer used to determine the refractive index and dextran, fructose, glucose, lactose and maltose content (%) of liquid. This IP65-rated digital refractometer features automatic temperature compensation (ATC) from +10-+40 °C / +50-+104 °F, as well as a large, easy-to-read LCD that shows both the measured value and the temperature. Refractometer is a multifunctional device, which by measuring refractive index is able to measure various parameters and in particular, sugar content in various liquids. Fructose level is one of the parameters, along with sucrose, glycose, invert sugars, which refractometer measure within seconds and very accurately. Knowing the level of fructose allows making conclusions about the quality and ripeness of the products, like different kinds of fruit. The optimal time of harvesting may be now determined not only by means of optical analysis and tasting, but also by means of application a fructose refractometer.

The level of fructose in the fruits changes with the time, and it is important to determine the best time with the optimal fructose content so that not only to deliver the best fruits to the consumers, but also to provide the best material for juices and jams production. In its natural condition, fructose is presented mostly in plants and fruits, in the industrial sphere; fructose is obtained from certain plants and is affected by lime. Due to its characteristics it is not used in the confectionary industry as a pure product, but is a part of the invert sugar; and under the influence of temperatures it is destructed much faster and dissolves in water much better than other substances (sugar, glycose). That is why, for the producers it is essential to know the amount of fructose in the raw material, so that they could clearly determine the conditions under which the manufacturing process will be the most effective and how particular amount of fructose will react.
