Frequently Asked Questions
What is a refractometer and how does it work?
A refractometer is an optical instrument used to measure the refractive index of a liquid. This refractive index is a crucial property that indicates how light behaves when it passes through the liquid. By analyzing the bending of light waves as they move from air into the fluid, the refractometer can provide precise measurements about the concentration of solutes in the solution, such as sugar or salt.
These instruments work on the principle of total internal reflection. When light enters a liquid droplet placed on the refractometer’s prism, it bends at a predictable angle, depending on the liquid’s density. The device then translates this angle into a specific measurement, which can be read directly from a scale or displayed digitally, allowing users to assess the liquid’s concentration with a high degree of accuracy.
