Kruss PRB21 Bypass Process Refractometers

Kruss PRB21 Series Bypass Process Refractometers

The bypass process refractometer PRB21 fills the gap between digital laboratory refractometers and process refractometers. The sample is directed through a bypass to the measurement chamber , while the prism is made of scratch-resistant sapphire.

The PRB21 is usually connected to a PLC and used for continuous process monitoring. The measurement interval is adjustable and the measurement result is not affected by the color or the turbidity of the sample. The PRB21 has multiple interfaces and can be supplied with PROFIBUS on request. A display is also available for monitoring.
