Information

ATEX-Sight glasses GN 546.6 are suitable for use in an explosion risk environment. They comply with the guidelines 94/9/EG.

A detailed operating instruction is included.

By virtue of the high strength of the material (considerably stronger than, for instance, Plexiglass) the oil level glasses can be produced in much thinner walled material which has also led to clearer sight. The ratio between bore Ø and the viewing window is much improved.

Assembly instruction:
For mounting on walls of less than 4 mm thickness please use a fixing nut GN 543.1.
