Transparent, semi transparent liquid or solid ST121A Abbe refractometer compression mechanism cold external circulation

ST121A Abbe refractometer is an instrument capable of measuring the refractive index ND and average dispersion NF-NC of transparent, translucent liquids or solids. With a thermostat connected to the instrument, it is possible to measure the refractive index ND at temperatures ranging from 0 ℃ to 70 ℃, and to measure the percentage of sugar content in the sugar solution from 0-95% (equivalent to a refractive index of 1.333-1.531). Therefore, this instrument is one of the indispensable equipment for factories, schools, and powder research units in the petroleum industry, oil and fat industry, pharmaceutical industry, paint industry, food industry, daily chemical industry, sugar industry, and geological survey.
