Kruss PR21 Series In-Line Process Refractometers

Kruss PR21 Series In-Line Process Refractometers

The PR21 has been developed for direct insertion into pipes and boilers, for process monitoring, control and separation of products in such industries as chemicals, beverages, food, pulp, paper, and sugar. Installation in a pipeline or tank is simple, as no bypass is necessary. Three interfaces are available for this unit: Analogue 0/4-20 mA, Ethernet, or PROFIBUS.
