Refractometers are precise measuring instruments used to determine the refractive index of liquids. They allow for quick and accurate analysis of liquids to measure various parameters such as salinity, sugar content, refractive index or even alcohol content. These devices are indispensable in various fields such as the food industry, pharmaceuticals, chemistry, water treatment and agriculture. With their easy handling and reliable results, refractometers offer an efficient solution for anyone who needs accurate measurements of liquid compositions. They are available in both handy, portable versions for mobile use and professional, stationary models.
