Product Description
2WAJ The instument serves for measuring the refractive indices nD and mean dispersions nF – nc of transparent and translucent liquid or solid, mainly the transparent liquid.. Attaching a thermostat to this instrument, the refractive indices nD within the range of temperature 0°C – 70°C can be measured. Refractive indices and mean dispersions belong to one of the important optical constants in substance, which can be used to determine the optical performance, purity, concentration and dispersion etc. The instrument in saccharo se solutions (0-95%，equal to refractive indice 1.333-1.531). Therefore, this instrument can be widely used 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 survery.
