ACETEQ- Digital Hand Held Refractometer Brass Series 0-90% BRIX (BR90B)

 
A refractometer is a scientific instrument used to measure the refractive index of a substance. The refractive index is a measure of how much light bends or refracts when passing through a substance. Refractometers are commonly used in fields such as chemistry, biology, food science, and agriculture to measure the concentration of dissolved solids in a liquid sample. For example, a refractometer can be used to measure the sugar content of fruits or the salinity of water.
