Why Choose a Viewing Mirror?
The main advantage of a Viewing Mirror / Sanitary Sight Glass is that it allows operators to visually monitor a closed process line without disconnecting or opening the piping system.
The stainless steel construction provides corrosion resistance, while the transparent viewing section makes it easier to monitor fluid movement and process conditions.
For specific applications, the glass material, sealing components, connection size, pressure rating, and operating temperature should be selected according to the actual process requirements.
