WebAug 11, 2014 · Last Updated: 2014-08-11. Refractometers are instruments to measure substances dissolved in water and certain oils. The refractometer works using the principle of light refraction through liquids. As light passes from air into a liquid it slows down. This phenomenon is what gives a "bent" look to objects that are partially submerged in water. WebRefractometry is a technique that measures how light is refracted when it passes through a given substance. Snell’s Law which is also known as The Law of Refraction describes the …
