ST121A Abbes Refractometer
The ST121A Abbe refractometer is an instrument capable of measuring the refractive index ND and the average dispersion NF-NC of transparent or semi-transparent liquids or solids. When equipped with a thermostatic device, it can determine the refractive index ND within a temperature range of 0°C to 70°C and measure the sugar concentration in a solution from 0% to 95% (corresponding to refractive indices of 1.333 to 1.531).
Therefore, this type of instrument is an indispensable essential equipment for factories, schools, and research institutions in the petroleum industry, oil refining industry, pharmaceutical industry, paint manufacturing industry, food industry, daily chemical industry, sugar industry, and geological exploration.
