Description
Overview
GAOTek Fully Automatic Refractometer features a high-performance linear CCD sensor and incorporates advanced semiconductor temperature control. Utilizing rapid and precise signal acquisition, analysis, and processing technology, this refractometer accurately and efficiently measures the refractive index (Nd) and mass fraction of sugar solution (Brix) in a wide range of liquids, including transparent, translucent, dark, and viscous substances. Its applications span various industries, including petroleum, oil, pharmaceuticals, food, daily chemicals, and sugar. Additionally, it is commonly employed in educational institutions and research units. In the food industry, it ensures quality control of raw materials, intermediates, and final products, measuring concentrations of dry matter, solids, and sugars, and assessing purity in sugar, dessert, beverage, dairy, chocolate, and coffee, as well as in the oil and fat sectors. In the pharmaceutical industry, the refractometer aids in determining solid content in blood and urine and facilitates purity control. In the cosmetics industry, it determines the refractive index of essential oils and spices and assesses the fatty acid content of soap and fragrance ingredients. Furthermore, in chemical and petrochemical industries, it plays a vital role in determining the refractive index of raw materials and analytical reagents, ensuring purity control, measuring the refractive index of petroleum products, and determining the concentration of cooled lubricating oil.
