Applications:
The instrument serves for measuring the refractive indices nD and mean dispersions NF - Nc of transparent and translucent liquids or solids, mainly the transparent liquid. Attaching a thermostat to this instrument, the refractive indices nd within the range of temperature 0^oC ~70^oC can be measured. Refractive indices and mean dispersions are one of the important optical constants in substance, which can be used to check in substance optical performance, purity, concentration and dispersion etc. The instrument is capable of determining the percentage of sugar content in saccharose solutions. Therefore, this instrument has wide use as one of the indispensable tools in petrological, oil and fat, pharmaceutical, paint, food, chemical and sugarmaking industries as well as in the factories, colleges and research institutes concerned with geological surveys.
