K-Patents is a leading supplier of process refractometers for industrial process monitoring and control. The refractometers are used for measuring concentration in solutions in all types of liquids and mixtures.

K-Patent’s refractometer provides a reliable and precise real-time measurement, ideal for process optimization and control. Product quality and batch times are controlled more precisely and costs are reduced. Time-consuming and expensive sampling is replaced by a continuous inline refractometer measurement, which is practically service and maintenance-free.
