ST121A Abbe refractometer
The ST121A Abbe refractometer is an instrument capable of measuring
the refractive index ND and average dispersion NF-NC of
transparent, semi transparent liquids or solids. If a thermostat is
connected to the instrument, the refractive index ND can be
measured within the temperature range of 0 ℃~70 ℃, and the
percentage of sugar concentration in the sugar solution can be
measured from 0-95% (equivalent to a refractive index of
1.333-1.531). Therefore, this type of instrument is an
indispensable equipment for factories, schools, and powder grinding
units in the petroleum industry, oil and fat industry,
pharmaceutical industry, paint industry, food industry, daily
chemical industry, sugar industry, and geological exploration.
