Spectrum Taso Spoon and Probe Holder

The Spectrum TASO Probe Holder is designed to integrate standard NIR, UV, Raman and Particle size analyser probes at adjustable depth into your process stream by means of a standard 2” Hygiene Tri Clamp process equipment port. The device is designed to allow collection of a sample from a dispersed product stream such that a good PAT measurement may be made. The Spectrum TASO is designed to replace this collected sample periodically whilst simultaneously wiping the face of the PAT probe as the spoon is emptied.

The probe holder is heated to reduce the possibility of material sticking to probe window or the device itself. The device is constructed from fully traceable and certified FDA approved materials. Air actuation of the device allows safe use of the Spectrum Probe Holder in ATEX Zone 21/22 process environment.
