Available in six standard sizes that provide viewing areas ranging in size from approximately 3″ to 9″ in diameter. This weld-on assembly is designed to provide direct visual inspection of process vessels, separators, silos, pipelines and storage tanks.
To illuminate the interior of the vessel, an optional LumiStar Light allows viewing and lighting through the same port, saving the additional expense of a separate light port. Explosion proof lights, see USL05-Ex, and non-explosion proof lights, see USL13, are available as well. For a full selection, see Illumination Sources. To remove condensation and product build-up on the inside of the glass, try this unit in combination with Wiper Type I, Wiper Type II, or a spray nozzle.
