1. Use
The 2W Abbe refractometer (binocular) can measure the refractive index ND and mean dispersion NF—NC of transparent, translucent liquids or solids. The instrument can also be equipped with a thermostat, which can measure the refractive index ND within the temperature range of 0°C to 70°C, and measure the percentage of sugar concentration in the sugar solution.
Therefore, this kind of equipment is one of the indispensable common equipments for factories, teaching and scientific research units in petroleum industry, oil industry, pharmaceutical industry, paint industry, food industry, daily chemical industry, sugar industry and geological survey. The classic model of the original Abbe refractometer series.
