the principle of hand-held Brix refractometer
When light is transferred from one medium to another, it causes reflections, and the sine ratio of the angle of incidence is stationary. This ratio is called the refractive index. Under certain conditions (similar temperature and pressure), the content of soluble solids in fruit and vegetable juice is proportional to the refractive index. Therefore, the concentration (sugar content) of fruit and vegetable juice can be obtained by measuring the refractive index of fruit and vegetable juice. A common instrument is a hand-held refractometer.

The common instrument is a hand-held refractometer, also known as fruit sugar meter, digital refractometer, digital sugar meter, digital concentration meter, digital display refractometer, digital display refractometer, digital refractometer, digital display sugar meter, concentration meter. By measuring the soluble solids content (sugar content) of fruits and vegetables, we can understand the quality of fruits and vegetables and accurately estimate the ripeness of fruits and vegetables
