Why Choose a Sanitary Sight Glass?
The main advantage of a sanitary sight glass is that it allows operators to visually inspect the process without opening the piping system.
The transparent viewing section can help operators monitor fluid movement, flow condition, and product appearance, making it useful for process monitoring and equipment inspection.
The exact glass material, sealing components, pressure rating, connection size, and operating temperature should be selected according to the actual process requirements.
