Handheld Brix Meter Calibration and Temperature Correction Method and Precautions
Handheld Brix Refractometer Calibration and Temperature Correction Methods and Precautions for Use
1. Handheld Brix Refractometer 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.
2. Precautions for hand-held Brix Refractometer
The instrument is a precision optical instrument, the following matters should be paid attention to in the use and maintenance:
1). Must be careful and careful in use, use strictly according to the instructions, do not arbitrarily loosen the connecting parts of the instrument, do not drop, collide, and strictly prohibit violent vibration.
2). After use, it is strictly forbidden to directly put it into water for cleaning, and wipe it with a clean soft cloth. For the optical surface, it should not be bumped or scratched.
3). The instrument should be stored in a dry, non-corrosive place.
4). To avoid the loss of spare parts.
3. The sugar content on the market is divided into:
Non-destructive sugar meter: No need to cut the fruit, directly touch the probe to the surface of the fruit to be tested to measure the sweetness of the fruit.
Portable sugar content measurement: Before picking fruit, measure the sweetness of the fruit to ensure the uniformity of sweetness and improve the production management goals of crops.
Computer Brix Tester: Each fruit is tested for sweetness, according to quality inspection, grading, processing and packaging operations, which can increase the high selling price.
