Raman Rxn-41 Probe

Brand: Endress+Hauser

The Raman Rxn-41 probe is a rugged, process insertion probe with no sample handling system. Its single cable design streamlines installation, eliminates risk scenarios, and minimizes installation cost for long fiber runs in the process environment. The Rxn-41 probe is ideally suited for use in chemical plants and refineries to measure batch or continuous flow production. For direct measurements in cryogenic fluids, an optimized cryogenic version of the Raman Rxn-41 probe is available.

Chemical: reaction monitoring, blending, feed and final product monitoring
Polymer: polymerization reaction monitoring, polymer blending
Pharmaceutical: API reaction monitoring, crystallization, polymorph, drug substance production unit operation
Oil & Gas: fuel blending, fuel characterization

Features
