78 EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A
Test gases
Analyzer Test gas for zero-point calibration
and single-point calibration
Test gas for end-point calibration
Caldos27 Sample component-free test gas or
process gas
Test gas or process gas with a known
sample gas concentration
Caldos27 with a suppressed
measuring range
Test gas with a sample component
concentration near the starting point
of the measuring range
Test gas with a sample component
concentration near the end point of
the measuring range
Caldos27 with single-point
calibration
Test gas with a known and constant
rTC value (standard gas; possibly also
dried room air)
–
Dew point
The dew point of the test gases must be approximately the same as the dew
point of the sample gas.
