Hand Refractometer

A hand refractometer is a portable, optical instrument used to measure the refractive index of liquids. It is commonly utilized in various industries such as food and beverage, agriculture, and automotive to determine concentrations of substances like sugar, salt, or coolant levels. The device works by placing a drop of liquid on its prism and observing the light’s refraction through an eyepiece. Its ease of use, quick results, and accuracy make it a valuable tool for quality control and fieldwork applications, ensuring consistency and precision in measurements.
