Description

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 fully automatic 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

High-Resolution Detection, Accurate and Efficient

Equipped with a high-resolution CCD detection system, it enables fast automatic measurements with excellent repeatability. The built-in temperature compensation function effectively minimizes human error, ensuring authentic and reliable data.

Minimal Sample Volume, Non-Destructive Recovery

Only 0.5 mL of sample is required for measurement. With a small liquid contact area, the measurement process is non-destructive, and the sample can be recovered and reused, helping to control experimental costs.
