In-Line Process Refractometers

Measure the refractive index in real time, determining the concentration of liquids or the mixing ratios of binary or quasi-binary mass ratios.

In-Line Process Refractometers

All the in-line process refractometers and sensors perform industrial measurements continuously and in real time. This technology is also known as PAT (Process Analytical Technology). PAT allows you to monitor and control your process without product loss or process divergence.

These process sensors and refractometers allow quality control and the determination of liquid concentration and mixing ratios becomes easy: Measurements are always reliable an independent of turbidity, color, absorption and viscosity – ensuring maximum precision and better control of your processes.

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