What is the difference in use and principle between a hand-held sugar meter and a hand-held refractometer?
1. Different functions
Hand-held sugar meter: Hand-held sugar meter is used to conveniently and quickly determine the weight percent concentration or refractive index in sugar-containing solutions.
Handheld refractometer: It can be used to measure the refractive index of liquid, the solute content in solution, the sugar content in wine, the water content in high sugar solution, the salinity of seawater and the specific gravity of battery electrolyte, etc.
2. Different working principles
Hand-held sugar meter: The sugar 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 measured by using 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.
Handheld refractometer: 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. The instrument can also measure the percentage of sugar content in the sucrose solution.
