Refraction occurs when light enters another medium from one medium, and the ratio of the sine of the incident angle is constant. This ratio is called the refractive index. fruit
The content of soluble solids in vegetable juice is proportional to the refractive index under certain conditions (same temperature and pressure), so the refractive index of fruit and vegetable juice is determined.
rate, the concentration (sugar content) of fruit and vegetable juice can be obtained. Commonly used instruments are hand-held refractometers, also known as sugar mirrors and hand-held saccharimeters.
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 roughly estimated. hand-held sugar meter
It is cylindrical, put the sugar liquid to be tested into the openable groove at the back, spread it evenly, close the lid, and then point the sugar meter to the light, from the front
Look in the hole and you can read it.
