VTSYIQI Binocular Refractometer Abbe Refractometer with Accuracy ±0.0003 Refractive Index nD 1.3000-1.7000nD Digital Thermometer for Sugar Pharmaceutical Beverage Petroleum Food Chemical Industries

Purpose：

The Abbe Refractometer is intended for measuring the refractive index nD and the average dispersion nF- nC of transparent or translucent liquid, or solid substance (of which mainly intended for measuring transparent liquid).

In case of the instrument being connected with a thermostat, it will be able to measure the refractive index nD at a temperature between 10℃ and 50℃.

Both the refractive index and average dispersion are the important optical constants, through which we can understand the optical performance, purity, concentration, as well as dispersion of a substance. In this instrument, based on the formula provided by the international commission of uniform method of sugar analysis (ICUMSA) in 1974, the refractive index is converted into the mass fraction (Brix) of cane sugar solution, with a range of conversion from 0-95%.

Therefore, this instrument has found an increasingly wide utilization in the fields as petroleum, oil, pharmaceutical, paint, food, chemical and sugar refining industries, as well as in geological prospecting enterprises, colleges, universities and scientific research institutions.
