Gas connections
Depending on the conguration of the unit
(number of measurement channels and serial
or parallel connection), sample and calibra-
tion gases are fed into the unit via up to 8
tube ttings mounted on the rear panel. The
conguration of the ttings is indicated on an
adhesive label located near the tube ttings.
Any free tube ttings can be used for purging
the device with
•
inert gas to minimize interference from the
ambient atmosphere when measuring small
concentrations (e.g. of CO
2
)
or
•
air or inert gas when measuring corrosive
and/or ammable gases.
For further information, see page 1-5.

Special components
For the analysis of aggressive and/or am-
mable gases, infallible components (WLD;
photometer under development) can be used.
The risk of an uncontrolled release of gases
due to a leak can be minimized by the use
of stainless steel piping and clamping rings.
Further details about the infallible contain-
ment are in the separate manual supplied with
units containing such parts.
Furthermore, intrinsically safe measuring
cells, which prevent the ignition of gas mix-
tures in the case of a failure, can also be
used.
Modul variation XCC
The ½19-in unit is also available as an ana-½19-in unit is also available as an ana-
lyzer module without the front control panel,
which can, for example, be integrated into a
measuring system in which control and ana-
lysis of data is performed via interface by an
external data acquisition system.
