Characteristics and working principle of sugar meter
Sugar meter is used to quickly measure the concentration or refractive index of sugar-containing solutions and other non-sugar solutions. It is widely used in sugar, food, beverage and other industrial sectors as well as in agricultural production and scientific research. It is suitable for the concentration measurement of various sauce (seasoning) products such as soy sauce and ketchup. It is suitable for the sugar content measurement of products with high sugar content such as jam, syrup, liquid sugar, etc. It is suitable for the production line of fruit juice, refreshing drinks and carbonated drinks. , quality management, pre-shipment inspection, etc., suitable for the process of fruit from planting to sales. It can be used to determine the accurate harvesting period and classify sweetness. In addition, the concentration determination of slurries in the textile industry has also been widely used.
When light enters another medium from one medium, refraction occurs, and the ratio of the sine of the incident angle is constant. This ratio is called the refractive index. The soluble solid content in fruit and vegetable juices is directly proportional to the refractive index under certain conditions (same temperature and pressure). Therefore, by measuring the refractive index of fruit and vegetable juices, the concentration (sugar content) of fruit and vegetable juices can be found. A commonly used instrument is a handheld refractometer, also known as a sugar mirror and a handheld sugar meter. 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 the fruits can be roughly estimated. A handheld sugar meter is generally cylindrical. Place the sugar solution to be measured into the slot that can be opened at the back, spread it evenly, close the lid, then hold the sugar meter up to the light and look through the hole in the front to read.
