All in-line process refractometers and sensors provide continuous, real-time industrial measurements. This technology, known as PAT (Process Analytical Technology), enables efficient monitoring and control of your production process, minimizing product loss and preventing process divergence.
These process sensors and refractometers simplify quality control and make it easy to determine liquid concentrations and mixing ratios. Measurements remain reliable regardless of turbidity, colour, absorption, or viscosity. This ensures high precision and optimal process control.
Applications for process refractometers and sensors
An important area of application is food analysis, for example, the investigation of oils and fats, sugar, and sugar-containing substances. Beer and spirituous beverages also belong to the material classes investigated by refractometry, along with applications in clinical chemistry.
Furthermore, refractometers are used as universal detectors for analyzing liquids.
Process refractometers can be installed in pipelines, mixing tanks, reaction boilers, storage vessels, cooking appliances, or evaporators using a variety of flange connections.
