In all honesty, we had no idea refractometers had so many uses in so many different industries:
- Automotive industry uses refractometers to analyze antifreeze and transmission fluids
- Wine growers use refractometers to measure the amount of sugar in their product at various times
- Environmentalists an use refractometers to measure the salinity (saltiness) of water.
- … and the list goes on.
Refractometers work on the principle of refraction, or the bending of the path of a beam of light as it passes through a medium of some sort. Different mediums will cause the light to bend in different amounts and thus a direct relation between concentration and changes in light path exists.
