PL80/NW50 Sight Glasses with Light

Observing the contents in a processing vessel normally requires the use of two Sight Glasses: one for lighting, the other for viewing. The Series PL/NW eliminates the expense of an additional port and the expense to install it. The UL-1571 Listed Series PL lighting unit and the corresponding Series NW sight glass provide glare-free illumination precisely where you want it – at the viewing port.
