Description

Technical Field

[0001] The utility model relates to the technical field of sugar content detectors, in particular to a digital display sugar content detector. Background Art

[0002] When light passes from one medium into another, refraction occurs. And the ratio of the sine of the incident angle to the sine of the refraction angle is a certain value, which we call the refractive index. The soluble solid content (i.e., sugar content) in fruit and vegetable juice is proportional to the refractive index under certain conditions (same temperature, same pressure), so by measuring the refractive index of fruit and vegetable juice, the concentration of the fruit and vegetable juice (the amount of sugar content) can be calculated. The traditional Abel refractometer can measure the sugar content and refractive index of the solution, but the Abel refractometer is large in size, complicated to operate, relatively time-consuming, and inconvenient to use. Therefore, there is an urgent need for a sugar content detector that is easy to use and detect. Summary of the invention
