Note:
Refractometers hand held precision for simple manual measurement of concentrations and refractive indices of liquids. Hand held precision with focusing eyepiece soft rubber eyecups (to reduce straylight ingress also spectacle lenses do not slip off and are not scratched) case and conversion tables.
This instrument always used to determine substance content in a sample, to provide unit readings of substances including Brix, salinity, and alcohol; to detect chemical impurities, or to measure components of samples such as industrial fluid.
It measures the refractive index of a substance, which is its optical characteristic, and the number of dissolved particles in it. The refractive index is the ratio of the speed of light in empty space to the speed of light in a substance; when light passes from one medium to another.
Generally, a low concentration sample has a larger angle of refraction than a high concentration sample. For example, a straw placed in a high-concentration substance appears more bent than when placed in a low-concentration substance.
It can work with natural light, or with an external power source such as batteries or electricity. They typically have either a digital or analog reading display, though some units utilize both types. Some analog-display can be used for both solids and liquids. Digital-display are used exclusively for liquids.
