Refractometry - the method of measuring substances refractive index by refractometer. A Refractometer is a special tool designed for the measuring of the liquid characteristics using the light refraction. Although at first sight appear all optical refractometers the same they differ in the optical part.
The primary function of a refractometer is to measure the refractive index of a sample. The refractive index is a measure of how much light changes direction as it moves from one medium to another. This change in direction occurs due to the differing densities of the two media. The refractive index is calculated using Snell’s Law, which .
Refractometers enjoy popularity in many applications, each of which has slightly different requirements for the instrument. Read on to learn more about the different types of refractometers, such as Abbe refractometer, hand refractometer, digital refractometer, automatic refractometer, and process refractometer. Figure 1: A Brix reading through optical Brix Refractometer. Digital Refractometers. In a similar way to optical refractometers, you take a Brix measurement using a digital refractometer by first placing the sample within a receptacle (some have covering lids, and some do not). The digital refractometer will then produce its own LED light and . An analog refractometer requires no external power source to function. To obtain a Brix reading for a solution, a few drops are placed on top of a prism, which is then covered by a lid. The refractometer is then brought up .
A refractometer is a device for measuring the index of refraction of a liquid sample, which is the ratio of light’s velocity in a vacuum to its velocity in the sample.
