Sight glass

See what's going on

Sight glasses and double-sided viewing glasses allow you to quickly and visually inspect your ongoing processes. Equipped with the appropriate measuring and control systems, you always have the full overview of your medium. Our long-life LED lighting provides additional visibility of the process medium.

The lighting element is available as a halogen or energy-saving LED lamp. The LED light source has numerous advantages over conventional halogen lights. In addition to a significantly longer life and lower power consumption, LED is characterised by its low heat generation. This "cold light feature" prevents burning on the sight glass.

• Affordable visual control

• 2 device connections with grooved nut screw connection
