refractometers
Optical density instruments
Refractometers are instruments that measure how much light bends when passing through a substance.
Since the degree of refraction depends on a material's composition and concentration, refractometers help determine the sugar content in wine, the salinity of seawater, or the purity of gemstones.
Handheld versions let winemakers and beekeepers take readings in the field.
