Refractometer is a type of device that tests the concentration of dissolved substances inside solutions.
Types of solutions that can be measured with a refractometer include: fruit juices, milk, cutting oils, cosmetics, etc.

The operating principle of refractometers (mechanical and electronic types) is based on Snell's law or the law of light refraction.
The refractive index (n) of a substance relative to air is calculated as the ratio between the sine of the angle of incidence and the sine of the angle of refraction of a light beam passing from air into that substance. When going from an air medium into a medium other than a liquid (another medium), the light ray will be deflected by an angle called the angle of refraction.
When examining liquids with a refractometer, based on the deviation of the light rays, we can calculate the concentration of dissolved substances and from there calculate the percentage of water in the food.
ATAGO REFRACTOMETER APPLICATION
► Food industry:
In the food industry, commonly used refractometers are refractometers that measure salinity (Salinity) and measure sweetness (Brix) to check and evaluate the % concentration of input materials as well as the quality. Finished products of sugar, jam, dairy products, spices, sauces, etc.
Besides, refractometers can also be used in the production and processing of wine and alcoholic beverages to check and control the alcohol content of wine, beer, and juices.
