Planktovie - Model A011 -Grandbeing High Precision Refractometer (0-­30°C)

A refractometer is a precision optical instrument that operates on the principle- as the concentration or density of a solution increases, its refractive index changes proportionately. The refractive angle measured by refractometer registers on the scale. The larger the concentration of solute in the solution, the higher the reading on the scale.
