Abbe Refractometric Instrument

The Abbe refractometer determines the refractive index, sugar content, or concentration of transparent or translucent liquids by measuring the critical refraction angle of light as it passes from the liquid sample into a prism, utilizing the relationship between refractive index and solution concentration. It is commonly used for rapid on-site testing and quality control in industries such as beverages, chemicals, and pharmaceuticals.
Selection
When selecting, consider a measurement range that covers the common liquid refractive index of 1.3–1.7, with an accuracy meeting the basic requirement of 0.0001. Manual models are suitable for routine testing, while digital models facilitate easier reading. Temperature control functions are ideal for precise measurements. For small sample volumes, opt for micro-volume models, and for on-site testing, consider portable designs.
