Listed at 415.00 USD. 1111MicrosoftInternetExplorer402DocumentNotSpecified7.8 磅Normal0 The instrument 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 is capable of determining the percentage of sugar content in saccharose 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 industriesas well as in the factories,olleges and researtch institutes concerned with geological survery. Features：Determine the refractive index nD average dispersion of liquid or solid (nF-nC) and the mass fraction of dry solids in aqueous sugar solution, i.e., the hammer degree Brix, which can be used for testing and analysing in the production, scientific research, and teaching departments of sugar, pharmacy, beverage, petroleum, food, and chemical industries. Adopt visual aiming and optical disc reading, simple and reliable.
