Process refractometer PR21

The PR21-series has been developed for direct insertion into pipes and boilers. It measures the refractive index with high accuracy and enables sophisticated process monitoring in the food, sugar, beverage, chemical, textile, paper, metalworking and petrochemical industries. Measurements are not influenced by color or turbidity. The instrument is also ideal for waste-water control and a number of other quality inspections.
Installation of the process refractometer is simple and fast due to the use of standardized flanges. It can be connected to a PLC by analog interface or PROFIBUS (available optionally).

In addition to its up-market PR21 Process Refractometer A.KRÜSS has launched the PRB21 bypass process refractometer to meet all requirements in basic process monitoring.
