Web14. jan 2024 · Refractometers measure how much light bends, or refracts, when it enters the liquid. This is called the refractive index. The more salts (and other material) dissolved in the water, the more resistance the light will meet and the more it will bend. This is because light travels at different velocities depending on the medium.
