Sight glass, also known as a sight window or sight port window, is a visual observation window made from a robust glass substrates is useful to verify conditions in piping, vessels, chemical Reactors or other industrial equipment. Sight glass is generally subjected to elevated temperatures, chemical attack and high pressure. So selecting the appropriate glass substrate is critical in order it to ensure safety even in the harshest of environmental conditions.
