The Raman Rxn-30 probe has cross-industry appeal for its robust gas-phase headspace monitoring, in situ measurements, and material compatibility. Certified for use in hazardous area environments, the Raman Rxn-30 probe can be inserted directly into processes with temperatures up to 150 degrees Celsius and pressures up to 68.9 barg (1,000 psig). It is available with a variety of mounting options for maximum installation and sampling flexibility.
Raman spectroscopy from Endress+Hauser has established itself as a key PAT tool at Evonik. It enables significant efficiency gains, cost reductions, and faster market launch of new products.
