9.4 OXYMAT 7 / ULTRAMAT 7: Introduction of reference gas

Ensure that gas sampling devices, gas cooling devices, condensate vessels, filters and any
connected controllers, recorders or indicators are ready to operate (see the associated
operating instructions).
In the case of toxic, corrosive and/or combustible gases, ensure the suitability for use of the
components. They must be approved for the respective application.
Note
Introduction of corrosive gases into heated devices
The device operator is responsible for the temperature control of moist corrosive gases. The
heating of the gases starts at the sample gas inlet into the analyzer module.
Heated devices must always be purged during operation with corrosive gases.

Note
Composition of the reference gas
Using an unsuitable reference gas can cause the reference gas throttle (capillary tube) to be
closed. The device is then no longer capable of measuring.
Therefore, use dust-free reference gas or a standard dust filter with a mean pore width of
<5 µm in the reference gas inlet.
