Refractometry - The technology for measuring liquid concentrations inline

Why is refractometry, or refractive index measurement, the best choice?

Historically, Brix is a measure of the concentration of sugar in a solution. A higher sugar concentration causes a higher refraction of the light you shine on it. This refraction is traditionally measured with a refractometer. Nowadays, the term Brix is generally used to express the amount of dissolved substance. Whatever that substance or substances in the solution may be. It is entirely up to you how you interpret this value. The current devices are fully digital and can be used inline in industrial processes.

Measuring Brix with a refractometer is based on the refractive index of the liquid. This is completely dependent on everything that is in solution. The big advantage of a brix measurement with a refractometer is that you can measure inline, without influence of pressure, temperature, crystals, colour, flow and gas bubbles. In addition, the refractometers of Vaisala K-Patents offer you a calibration-free measurement, which shows no drift over time.
