Classification of sugar meters:
Nowadays, with the development of science and technology, instruments and equipment are becoming increasingly intelligent. The sugar meter is also changing rapidly. There are several types of sugar meters available on the market, including handheld sugar meters, digital sugar meters, and non-destructive fruit sugar meters. The non-destructive testing instrument for fruit sugar content is a newly developed instrument by Zhejiang Topp Company, which uses near-infrared spectroscopy technology for non-destructive testing of fruit sugar content. It has the advantage of not needing to cut open the fruit, directly placing the probe on the surface of the fruit, and producing test results in 3 seconds. The development of sugar meters also represents the development of modern scientific instruments. Scientific instruments have increasingly attracted the attention of various departments, units, and even people from all walks of life. This is because since KFC's Sudan Red, Sanlu's melamine, the recent arsenic scandal at Nongfu Spring, and the frequent incidents of water infused meat, toxic dumplings, and lean meat powder, people have lost confidence and become more fearful about the food they use in their daily lives. How to improve the quality of our food will be a question that the whole world and humanity will explore together. We look forward to more and more green food being introduced to ensure our lives and health.
Principle of handheld sugar meter:
Everyone knows that when light enters another medium from one medium, refraction occurs. The ratio of the sine of the incident angle i to the refractive angle r is a fixed value, which is the relative refractive index of light in these two media. It is expressed by the formula: n=sini/sinr. The refractive index, also known as refractive index, is actually the same principle. In the field of agriculture, it is often necessary to measure the sugar content of fruits and vegetables, because the soluble solid content in fruit and vegetable juice is directly proportional to the refractive index under certain conditions. Therefore, as long as the refractive index of fruit and vegetable juice is measured, the concentration of fruit and vegetable juice, that is, the sugar content of fruit and vegetable juice, can be obtained. Therefore, handheld sugar meters actually use the principle of light refraction to determine the sugar content of fruits and vegetables.
The principle of handheld sugar meters is very simple, so nowadays, there are many handheld sugar meters on the market, including different manufacturers and models, such as handheld refractometers, WZ series handheld sugar meters, GMK-706R sugar acidity meters, etc. Different models of sugar meters can measure different sugar content ranges. The handheld sugar meter has been widely used in industries such as industry, agriculture, sugar making, machinery, and chemical engineering. By measuring the sugar content of fruits and vegetables, the quality of fruits and vegetables can be understood, and the maturity of fruits can be estimated.
