WEGER is constantly improving its products and one of its latest innovations concerns sight glasses: The new version is square in size with rounded corners, and features and integrated LED light. This provides a number of advantages, as the LEDs use very little energy and can easily be changed, if necessary.

In small and medium-sized units, they even replace lighting equipment inside the unit, saving money. With a side length of 282mm, the field of vision is 41% larger that with the round version, facilitating inspection and maintenance.
