Refractometer purpose

WebRefractometer definition, an instrument for determining the refractive index of a substance. See more. WebThe refractometer is a well-established instrument used for measuring the water content of liquids. It measures the refractive index of the liquid, which changes according to the moisture content. Moisture-related energy absorption of near-infrared light can be used for measuring the moisture content of solids, liquids, and gases.
