PolariMeter RefractoMeter

A polarimeter measures the angle of rotation of polarized light by a substance to analyze the content of optically active substances, and is used for detecting the concentration of sugars and pharmaceuticals. A refractometer determines the refractive index of a solution by utilizing the refraction of light at the interface between different media, enabling rapid detection of concentrations in juices and chemical products. Both instruments achieve non-destructive analysis of liquid components through optical principles.
Selection
Selection based on the characteristics of the tested substance: A polarimeter is suitable for optically active substances such as sugars and amino acids, while a refractometer is suitable for measuring the concentration of various solutions. Considering sample state and measurement range, the polarimeter requires transparent liquids, whereas the refractometer can measure viscous liquids. Operating conditions require the polarimeter to be protected from vibration, while the refractometer requires temperature control. For routine quality control, a refractometer is preferred, while for specific optically active substances, a polarimeter is recommended.
