Calibrate and use precautions of hand-held Brix refractometer
Prior to measurement, the zero point must be calibrated on the portable Brix refractometer calibration and temperature correction instrument. In order to set the dividing line to the 0% point of the scale, take a few drops of distilled water, place them on the detecting prism, and turn the zero adjustment screw. After that, inspect after cleaning the inspection prism. For some instrument models, standard solution must be used during calibration instead of distilled water. Use the temperature correction table to add (or remove) the temperature correction value from the value obtained at ambient temperature in order to obtain an accurate reading. This approach is solely appropriate for the assessment of sugar content.
