Uras26 + Magnos206
(automatic calibration, i.e.
Magnos206 with single-point
calibration)
IR sample component-free test
gas with O
2
concentration in an
existing measuring range or
ambient air. Same moisture
content as process gas.
Calibration cells or span gas*
Uras26 + Magnos206
(manual calibration)
Zero reference gas for Uras26 or
Magnos206, or IR sample
component-free test gas with O
2
concentration in an existing
measuring range or ambient air.
Same moisture content as
process gas.
Span gas for all sample
components in the Uras26 and
Magnos206 (possibly only for the
Uras26 if a single-point
calibration is carried out for the
Magnos206)
Uras26 + Caldos27
(automatic calibration, i.e.
Caldos27 with single-point
calibration)
IR sample component-free test
gas with a known and constant
rTC value (possibly also dried
room air)
Calibration cells or span gas*
Uras26 + Caldos27
(manual calibration)
Zero reference gas for Uras26 or
Caldos27, or IR sample
component-free test gas with a
known rTC value
Span gas for all sample
components in the Uras26 and
Caldos27 (possibly only for the
Uras26 if a single-point
calibration is carried out for the
Caldos27)
Uras26 + Caldos25
(automatic calibration)
Sample component-free test gas
or substitute gas for Uras26 and
Caldos25
Test gas or substitute gas mixture
for all sample components in the
Uras26 and in the Caldos25*
Uras26 + Caldos25
(manual calibration)
IR sample component-free test
gas for Uras26 and sample
component-free test gas or
substitute gas for Caldos25
Span gas for all sample
components in the Uras26 and
test gas or substitute gas with
known sample component
concentration for Caldos25
* Test gas mixture for multiple sample components possible if no or
negligible cross-sensitivity is present
