The Papalias Series QSG, is a light/sight glass combination, and the series LQSG are the quick release handle mechanism with hinge assembly type. When the handle is released, the sight glass may be pivoted off the lower flange, offering unobstructed and easy access to the interior of a vessel for sampling, cleaning or maintenance work. These sight glasses are ideally suited wherever samples must be taken during a process which is being carried out at low pressure or under vacuum conditions. Engineered from stainless steel and carbon steel as standard, with the lower sight glass flange constructed from aluminum casting. Additionally, virtually any machinable alloy can be specified to meet user requirements, offering a great variety. The sight glasses are rated standard for 7 PSIG (0.5 Barg) pressure at 300 degrees Fahrenheit (149 degrees celsius). Benefits from a high intensity 120V/100W halogen lamp providing bright illumination, ans a built-in momentary on/off switch for energy savings and increased lamp life.
