Nar-1t Solid Abbe Refractometer is a kind of refractometer that is mostly utilized in the industry of food, chemical, and pharmaceutical for measuring the refractive index of solids and liquids. It is a precision device that offers accurate and reliable measured results of the refractive index of a substance. This type of instrument is ideal to be utilized for the measurement of the refractive index of solid samples, like crystals or powders. In addition, Solid Abbe Refractometer is especially useful to measure the refractive index of translucent or transparent substances, such as glass, plastics, and polymers.
