Sight glass – also known as viewing glass, peep hole glass or inspection glass – are used to inspect or monitor a process. It could be a liquid in a container.

Sight glass is typically used to keep instruments or measuring devices separate from industrial processes and to monitor :
- As a level indicator in liquid substances as oil (controlled with an oil level glass), water (controlled with a water gauge), chemicals or liquid foods (flow gauge) . These can be checked with inspection glass, either as flat glass or sight glass in tubes.
- Solid masses and materials such as grain in a grain silo or cement in a tank.
- Combustion processes with high temperatures, where an inspection glass is needed
- Freezing processes
- As Food Contact Material (FCM). For example in a flow indicator or a level gauge
- Air, gases or heat – possibly under pressure / vacuum (eg a vacuum chamber)
- Many sectors use sight glass. For example the food industry, process industry, pharmaceutical, offshore, marine and transport (cars, boats, ships and aircraft). We supply sight glass to be used in ATEX areas (to monitor explosion safe facilities).
