Kaiser Raman WetHead Probe

Designed to promote versatility and materials compatibility

The WetHead probe is a compact, sealed immersion probe for in situ Raman spectroscopy of liquid-phase samples in a laboratory or process plant setting. The process connection for the WetHead can be swaged, compression-mounted, flange-mounted, or installed in a Kaiser flow cell, and is NeSSI compatible. These versatile options allow for direct insertion in slip-streams, drain-values, reactors, circulation loops, blend headers, and inlet or outlet pipework.

The WetHead probe is available in two variations—the WetHead Max and the WetHead Mini—to aid customization to your process and offer greater sampling flexibility. In addition, the WetHead probe is compatible with installations in hazardous areas/classified environments.
