An Abbe refractometer is a scientific instrument used to measure the refractive index of a substance, which is the bending of light caused by changes in the speed of light as it travels through the substance. It measures the refractive index by passing light through the sample to be measured and measuring the angle of refraction of the light. The Principle is based on the law of refraction and usually includes a light source, a beam of light, a sample chamber and a measuring device. By measuring the angle of incidence and refraction, and using a reference material with a known refractive index, the Abbe refractometer can accurately determine the refractive index of the sample to be measured, which is crucial for analyzing the composition, concentration and optical properties of a substance. It is widely used in fields such as chemistry, food science, pharmacy and materials science, providing a powerful tool for research and quality control, helping scientists and engineers gain a deep understanding of the properties of different substances.
BM-2W Abbe refractometer is an instrument that can measure the refractive index nD and average dispersion nF-nC of transparent, translucent liquids or solids (mainly measuring transparent liquids). If a thermostat is connected to the instrument, it can measure the temperature. It is the refractive index nD within 0℃~70℃.
Refractive index and average dispersion are one of the important optical constants of a substance, which can be used to understand the optical properties, purity, concentration and dispersion size of the substance. This instrument can measure the percentage of sugar concentration in sucrose solution (0 to 95%, equivalent to a refractive index of 1.333 to 1.531). Therefore, this instrument has a wide range of uses. It is an indispensable and commonly used equipment in factories, schools and related research units in the petroleum industry, oil industry, pharmaceutical industry, paint industry, food industry, daily chemical industry, sugar industry, and geological survey. one.
