Oxygen Sensor
Integrated Gas Feed
Sample Gas Dew Point
Outlet Pressure
Flammable Gases
The oxygen sensor may not be used for the measurement of flammable
gases.
Other Requirements
The H O dew point of the sample gas must be at least 2 °C. The oxygen
2
sensor may not be used if the sample gas contains the following
components: H S, compounds containing chlorine or fluorine, heavy
2
metals, aerosols, mercaptans, alkaline components.
Flammable Gases
If the gas analyzer is equipped with an integrated gas feed it may not be
used for the measurement of flammable gases.
Note: The integrated gas feed can be installed in model EL3020 as an
option. It cannot be used in the EL3040 model or in conjunction with the
Limas23, ZO23 or Fidas24 analyzer.
The dew point of the sample gas must be at least 5 °C lower than the
lowest ambient temperature in the overall sample gas path. Otherwise a
sample gas cooler or condensate trap is required. Fluctuations in water
vapor content cause volume errors.
The outlet pressure must be the same as the atmospheric pressure.
