Usage and precautions of handheld sugar refractometer
The handheld sugar refractometer and temperature correction instrument need to calibrate the zero point before measurement. Take a few drops of distilled water and place them on the detection prism. Turn the zero adjustment screw to adjust the dividing line to 0% of the scale. Then wipe off the testing prism for testing. Some models of instruments require the preparation of standard solutions to replace distilled water during calibration. Another method is (only suitable for measuring sugar content): use a temperature correction table to add (or subtract) the temperature correction value read at ambient temperature to obtain accurate values.
Precautions for hand-held sugar refractometer The instrument belongs to a precision Optical instrument. Use and precautions of hand-held sugar refractometer:
During use, it is necessary to be careful and follow the instructions strictly. It is not allowed to loosen the connecting parts of the instrument, drop or collide, and severe vibration is strictly prohibited.
After use, it is strictly prohibited to directly put it into water for cleaning. A clean and soft cloth should be used to wipe it. For optical surfaces, they should not be bumped or scratched
The instrument should be stored in a dry and corrosion-free place. 4) Avoid losing spare parts.
The current sugar score on the market is: non-destructive sugar meter: without the need to cut the fruit open, the probe is directly placed on the surface of the tested fruit to measure its sweetness. Portable sugar content measurement: Before picking fruits, measure the sweetness of the fruits to ensure uniformity of sweetness and improve crop production management objectives. Computer sugar analyzer: Each fruit undergoes sweetness testing based on quality testing, grading, processing, and packaging operations, which can increase the selling price.
