EL3000 CONTINUOUS GAS ANALYZERS
An unimpeded exchange of air with the surroundings must be possible
around the gas analyzer from beneath (base plate) and from behind (gas
connections). The gas analyzer must not be put directly on a table. The case
apertures must not be closed. The distance to adjacent, built-in components
on the side must be at least 3 cm.
For installations in a closed cabinet, the cabinet must have adequate ventila-
tion (at least 1 air change per hour). The distance to adjacent, built-in com-
ponents underneath (floor plate) and behind (gas connections) must be at
least 3 cm.
Protection against mechanical damage
Due to the low mechanical stability of the display window, the gas analyzer
has to be installed and operated in such a way that mechanical damage to
the display window with an energy exceeding 2 J is ruled out.
Protection against UV radiation
Due to the low UV resistance of the plastic parts of the housing, the gas
analyzer has to be installed and operated in such a way that exposure to UV
radiation is ruled out.
