Test gas for zero-point calibration
and single-point calibration
IR sample component-free test gas
with O concentration in an existing

measuring range or ambient air. Same
moisture content as process gas.
Zero gas for Uras26, respectively
Magnos27, or IR sample compo-

ambient air. Same moisture content
as process gas.
IR sample component-free test gas
with a known and constant rTC value
(possibly also dried room air)

* Test gas mixture for multiple sample components possible if no
cross-sensitivity is present
Dew point
The dew point of the test gases must be approximately the same as the dew
point of the sample gas.
NOTE
The notes for calibrating must be considered.
The pressure sensor is installed in the gas analyzer ex works. Depending on
the version of the gas analyzer it is internally connected as follows:
 Internal gas lines made as hoses:
 Pressure sensor in the outlet of sample cell 1 with one sample cell
and with separate gas feed paths,
 Pressure sensor in the outlet of sample cell 2 with two sample cells
in series..
 Internal gas lines made as stainless steel pipes:
 Pressure sensor connected to a connection port via an FPM tube.
