The working principle and use of a handheld sugar meter
1. The working principle of a handheld sugar meter: When light enters one medium from another, it produces refraction, and the ratio of the incident angle sine is constant, which is called refractive index. The soluble solid content in fruit and vegetable juice is directly proportional to the refractive index under certain conditions (at the same temperature and pressure), which can determine the refractive index of fruit and vegetable juice and determine the concentration (sugar content) of the juice. Commonly used instruments include handheld refractometers, also known as fruit sugar meters, digital refractometers, digital sugar meters, digital concentration meters, digital refractometers, digital refractometers, digital refractometers, digital sugar meters, and concentration meters. By measuring the soluble solid content (sugar content) of fruits and vegetables, the quality of fruits and vegetables can be understood, and the maturity of fruits can be estimated approximately. Handheld sugar meters are generally cylindrical in shape.
2. Handheld sugar meter instrument structure: ① refractive prism ② cover plate ③ calibration bolt ④ optical system pipeline ⑤ eyepiece (visibility adjustment ring)
3. Instructions for using a handheld sugar meter: Open the cover and carefully wipe the detection prism with a soft cloth. Take a few drops of the solution to be tested and place it on the testing prism. Gently close the cover to avoid bubbles and spread the solution over the surface of the prism. Align the instrument's light inlet plate with the light source or bright spot, observe the field of view through the eyepiece, and rotate the eyepiece to adjust the handwheel to make the blue white boundary of the field of view clear. The scale value of the boundary is the concentration of the solution.

The following precautions should be taken when using and maintaining the fruit sugar meter:
1. 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 violent vibration is strictly prohibited.
2. 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.
3. The instrument should be stored in a dry and corrosion-free place.
4. Avoid losing spare parts.
