ULTRAMAT 7 pressure correction
If you are using the analyzer module with atmospheric pressure sensor, make sure that the
pressure drop caused by the piping system at the sample gas outlet does not exceed 10 hPa
(large line diameter, short line length). In analyzer cabinets and analyzer enclosure, you can
connect the pressure transducer to the atmosphere in order to record only the atmospheric
pressure change.
