The transparent translucent liquid or solid refractive index ND and the average
dispersion NF-NC were measured. The instrument was also equipped with a
thermostat capable of measuring the refractive index ND at a temperature of 0-70
degrees and measuring the percentage of the sugar content in the sugar solution.

1, refractive index ND measurement range: 1.300~1.700
2, refractive index ND measurement accuracy: 0.0002
3, refractive index ND minimum division value: 0.0005
4, sugar concentration measurement range: 0~95%
5, the minimum concentration of sugar concentration: 0.25
