No Turbulence Sight Glass, Flush Window at Process Side

Smooth surface between the housing and the window. Sight glass PN100732

Notice the window is perfectly in-plane with the front of the metal housing at the process side. In other words, there is no space between the glass and the end of the metal fitting; the window is flush with the fitting's front. The sight glass does not protrude into the volume space, enabling turbulence-free observation of the process.

In-plane, flush to the front quartz sight glass for a flow tube Optical Cell.
