The SCHMIDT + HAENSCH electronic reflectance-meter for automatic color grading of crystalline sugar according to recommendations of ICUMSA, method GS2-11 (1994) and GS2-13 (1994). With this instrument the reflectance factors at 495 nm and 620 nm are measured and the ratio is indicated in terms of color type numbers. The consistent use of high integrated circuits, very little heating, and easily detachable lighting unit ensure that the Saccharoflex 2020 is a reliable and easily maintainable measurement system which corresponds to the high SCHMIDT + HAENSCH quality standard. Ceramic calibration standards are also available.
LCD display with four-button keyboard makes handling easy and standard serial interface RS 232 ensures proper printing. The adjustable working voltage provides a long service life of the lighting unit, thereby extending replacement intervals. In addition, the electric bulb is run by a power saving switcher which prevents the Saccharoflex 2020 from overheating, so that a continuous operation is possible without any problems.
The measurement is based on Taylor’s law and an integrating sphere. To decrease measurement instabilities caused by inhomogeneity of the sample (e.g. different grain size) a large sample surface is chosen.
Only two standards of the Brunswick color type or ceramic standards, preferably 0 and 6, are necessary to calibrate the Saccharoflex 2020. Adjustments can be made using the keyboard. The Saccharoflex 2020 allows measurements up to 19.99 color units (CU) without further adjustments.
