PRB21 bypass process refractometer

PRB21 is a basic bypass process refractometer, meeting all requirements in continuous process monitoring, filling the gap between the DR6000 series of digital laboratory refractometers and the PR21. It is cost-effective, easy to install, has a wide measurement range, and like the PR21 covers a large range of industry applications. RS-232 and analogue 0/4–20 mA interfaces are available for this unit, and PROFIBUS can be supplied upon request. For visual monitoring an optional display is also available.
