Principle and use of HB-110ATC sugar meter/refractometer
Instructions
Open the cover and carefully wipe the detection prism with a soft cloth. Take a few drops of the solution to be tested, put it on the detection prism, and gently close the cover to avoid the generation of air bubbles, so that the solution spreads over the surface of the prism. Aim the light inlet plate of the instrument at the light source or bright place, observe the field of view through the eyepiece, and turn the eyepiece to adjust the handwheel to make the blue-white boundary of the field of view clear. The scale value of the dividing line is the concentration of the solution.
Calibration and temperature correction
The instrument needs to calibrate the zero point before measuring. Take a few drops of distilled water, put it on the detection prism, and turn the zero adjustment screw to adjust the dividing line to the 0% position of the scale. Then clean the inspection prism and perform inspection. Some models of instruments need to be equipped with standard solution instead of distilled water when calibrating. Another method is (only suitable for the determination of sugar content): use the temperature correction table to add (or subtract) the temperature correction value to the value read at the ambient temperature to obtain an accurate value.
