Visual ABBE Refractometer, RFT-A Series

Refractive index and mean dispersion are key optical constants that characterize a material. Precisely measuring the refractive index not only helps identify substance purity and analyze optical performance but also accurately assesses its dispersion properties. Based on this principle, the abbe refractometer can accurately measure the refractive index of liquids at different temperatures. With its wide range of applications, it directly correlates with multiple critical parameters, such as the mass fraction of sucrose solutions, the solid content in soft drinks, and the water content in honey, providing reliable data support for quality control and process analysis.

Features

1. Utilizing a hard glass prism, it possesses excellent corrosion and scratch resistance.
2. Measurements can be completed with only 1-2 drops of sample, making it particularly suitable for the detection of precious or trace samples.
3. Equipped with a digital thermometer. The built-in flow cell can be used with a constant temperature bath to ensure measurements are performed under constant temperature conditions.
4. It is suitable for measuring the refractive index (nD), average dispersion (nF-nc) of transparent and semi-transparent liquids and solids, and mass fraction (Brix) of cane sugar solution.
5. The instrument features visual aiming and optical index-plate reading, ensuring easy operation and reliable results.
6. It is widely used in industrial sectors such as sugar, pharmaceutical, beverage, petroleum, food, and chemical industries, as well as in various research institutes and educational institutions.
