The difference between digital sugar meter and hand-held refractometer
1. Digital sugar content meter:
The digital display sugar meter is used to conveniently and quickly determine the weight percent concentration or refractive index in sugar-containing solutions. Widely used in sugar, food, beverage and other industrial sectors as well as agricultural production and scientific research.
Working principle: The sugar content meter mainly uses the refraction phenomenon when light enters another medium from one medium, and the ratio of the sine of the incident angle is constant, and this ratio is called the refractive index. The refractive index of the sugar solution can be determined by utilizing the direct ratio between the content of soluble substances in the sugar solution and the refractive index under ordinary circumstances, so that the sugar concentration can be calculated by the sugar meter/refractometer.
2. Handheld refractometer
Hand-held refractometer is an instrument that can measure the refractive index nD and average dispersion nF-nC of transparent, translucent liquids or solids (among them, transparent liquids are mainly used). If the instrument is connected with a thermostat, it can measure the refractive index ND within the temperature range of 0~70. Refractive index and average dispersion are one of the important optical constants of substances, which can be used to understand the optical properties, purity, concentration and dispersion of substances. Because the hand-held refractometer instrument can measure the percentage of sugar content in the sucrose solution, the hand-held refractometer is used in a wide range of applications. It is one of the indispensable and commonly used equipment for factories, schools and research institutes such as industrial and geological surveys.
