It is an important tool that determines the quality and grade of honey. . Aside from the Azzota refractometer, the package includes a cleaning cloth, a suction tube for dropping test fluids on the prism, a mini screwdriver for scale calibration .
A refractometer is a scientific instrument used to measure the refractive index of different materials – a value indicating how much the phase velocity of light is smaller compared with propagation in vacuum. Various refractometer types allow measurements in liquid, solid, or gaseous samples. Refractometers have a long history and a wide range of applications in .How to Use a Refractometer A refractometer measures the angle at which light rays refract “bend” as they move through a gemstone, and provide a reading (Refractive Index or R.I.) from a scale seen though the eyepiece of the refractometer. Because R.I. is unique for each type of stone, it helps to identify many stones.
