purpose
Measure the refractive index ND and average dispersion NF-NC of transparent, semi transparent liquids or solids. The instrument can also be equipped with a thermostat, which can measure the refractive index ND within the temperature range of 0 ℃ to 70 ℃, and measure the percentage of sugar concentration in the sugar solution.
Therefore, this type of instrument is one of the indispensable and commonly used equipment in factories, teaching and research institutions related to petroleum industry, oil industry, pharmaceutical industry, paint industry, food industry, daily chemical industry, sugar industry, and geological exploration.
