what does the refractometer measure
Describe the steps involved in using a refractometer and calibrating it with distilled water. A refractometer is a scientific instrument used to gauge a liquid's index of refraction. The refractive index is determined by placing a liquid sample on a prism and allowing light to pass through them to create a visible line on .Refractometers are used to measure the refractive index of a pure substance or mixture. Every substance has a unique refractive index that can be determined accurately. Refractive indices .
refractometer uses in laboratory
A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from the observed refraction angle using Snell's law.
