it works on the principle of refraction
There are four main types of refractometers: traditional handheld refractometers, digital handheld refractometers, laboratory or Abbe refractometers, and inline process refractometers. There is also the Rayleigh Refractometer used (typically) for measuring the refractive indices of gases.In veterinary medicine, a refractometer is used to measure the total plasma protein in a blood sample and urine specific gravity.
An Abbe refractometer is an instrument used to measure the refractive index of a liquid, by utilizing the critical angle for total reflection.
Some labs store the refractometer with a piece of tissue in the prism assembly to keep the prism glass from being scratched.
Any of several instruments used to measure the index of refraction of a substance. it is commonly known to be used in wine making, where the refractometer is used to measure the sugar content in the fruit juices.
A refractometer measures the refraction of light through a medium. In beer manufacture it tests for the density of sugars in the beer and is able to tell you the sweetness.

Oceanographers measure the salinity of the ocean by hand held refractometer, hydrometer, and conductivity meter.
A refractometer is a device used to read the refractive index (the degree to which light refracts/bends) in a liquid solution. It is often used to measure the sugar content of fruit, fruit juices, wine, milk, soft drinks and yeast cultures. Other applications include industrial cutting, salinity monitoring, battery acid, automotice coolant and clinical studies of urine.
