Inline Process Refractometer

Inline Process Refractometers measure the refractive index continuously and in real time, thus determining the concentration of liquids or the mixing ratios of binary or quasi-binary mass ratios.

The measurement is independent of turbidity, color, absorption and viscosity, which ensures maximum precision and better process control.

By using high quality materials and compliance of strict quality criteria, the highest reliability and precision of process refractometers is ensured.

Process refractometers can be installed in pipelines, mixing tanks, reaction boilers, storage vessels, cooking appliances or evaporators using various flange connections.
