A saccharimeter is an instrument for measuring the concentration of sugar solutions. This is commonly achieved using a measurement of
refractive index In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive index determines how much the path of light is bent, o ...
