Refractometers are used for the identification of substances and the measurement of concentration in fluids.
Because the refractive index (RI) of a solution is proportional to the concentration of a substance, it allows us to measure the purity and concentration of a solution.
Euromex optical/digital refractometers are calibrated at 20° Celsius. Most refractometers are equipped with automatic temperature compensation (ATC).
A refractometer is a laboratory or field instrument that measures refractive index (refractometry). The traditional handheld optical refractometer is an analog instrument for measuring the refractive index of a liquid. It is based on the principle whereby lenses and prisms project a shadow line at a critical angle onto a small glass grating inside the instrument, which is then viewed by the user through a magnifying lens.
