Use
It is used to measure refractive index ND and average color dispersion NF-NC of transparent and semi-transparent liquid or solid, also may be matched with constant temperature oven to measure refractive index ND with temperature 0℃-70 and measure sugar percent.
   Therefore, it is an indispensability equipment in common use in factory, teaching and science research related to oil industry, grease industry, pharmacy industry, pain-making industry, food industry, daily-use chemical industry, sugar-refining industry and geological reconnaissance, etc.
