Abbe Refractometer Refractometer is also called refractometer. It is an instrument that uses light to measure the concentration of liquid, and it is used to determine the refractive index, birefringence, and optical properties. Refractive index is an important physical constant when measuring substances. The so-called refractive index is the ratio of the speed c of light in vacuum to the relative speed v of light in the medium, that is n = c / v. There are many methods for measuring the refractive index of materials, such as total reflection method and minimum deflection angle method. The minimum deflection angle method has the advantages of high measurement accuracy, unlimited size of the measured refractive index, and can directly measure the refractive index of the measured material without the need for a standard specimen with known refractive index. However, the material to be tested must be made into a prism, and the technical requirements of the prism are not high, which makes it inconvenient for rapid measurement. The total reflection method is convenient and fast to measure, and has low requirements on the environment. No monochromatic light source and other features are required. However, because the total radiation method is a comparative measurement, its measurement accuracy is not high, the range of the refractive index of the material to be measured is limited, and the solid material also needs to support the test piece. Nonetheless, in some low-precision measurements, the total reflection method is still widely used. Abbe refractometer is an instrument made according to the principle of total reflection Abbe refractometer is an instrument specially used to measure the refractive index and dispersion rate of transparent or translucent liquids and solids. If a thermostat is connected to the instrument, the refractive index can be measured at a temperature of 0 ℃ -70 ℃. The instrument can measure the mass fraction of the sucrose solution (hammer Brix) (0-95%, equivalent to a refractive index of 1.333 1.531). Therefore, the instrument has a wide range of applications, and it is one of the necessary instruments for related factories, schools and related scientific research units in the petroleum industry, oil industry, pharmaceutical industry, paint industry, daily chemical industry, sugar industry and material survey. Our company recently launched several models of Abbe refractometer, first introduce one of them in detail-Abbe Refractometer DR-A1 With a simple operation, just set the refraction boundary line in the cross line, this refractometer can directly display the measured value (selectable refractive index or sugar content%) and temperature. No need to read the analog scale, anyone can easily complete the measurement. l This refractometer cannot measure the value of dispersion.
