Important information for photometer installation:
Scratches on the blanking glass can lead to incorrect measurements: Ensure
that no scratches occur on the blackened outer face and uncolored inner face
when installing and removing the blanking glass. Always handle the blanking
glass with care.
The outer face of the blanking glass is blackened with a PVD chrome coating.
The inner side of the blanking plate is sand blasted.
The photometer must be installed in the pipe at a point at least 2 m away from
inspection windows or other sources of stray light.
