Kaiser Raman Rxn4 process analyzer

Rugged, reliable Raman analyzer ensuring 24/7 process and quality monitoring

The Kaiser Raman Rxn4 analyzer is the optimal choice for manufacturing or process environments. Many companies move to the Raman Rxn4 after their processes have been successfully tested and proven in the laboratory or process development stages.

The Kaiser Raman Rxn4 provides high-resolution performance for in situ, real-time process measurement and control. It features unique self-monitoring, diagnostics, and self-calibration to ensure the validity of each measurement. Stackable in a standard 19″ rack, the Raman Rxn4 saves valuable space on the production floor. It is also offered with an optional stainless steel NEMA 4X enclosure.
