Mechanical installation

Gas connections

At least one sample gas inlet and one calibration gas inlet are always available, and up
to four additional gas inlets can also be used, e.g. for
• ULTRAMAT6/OXYMAT 6: at least one zero gas inlet (e.g. nitrogen)
• FIDAMAT 6: one hydrogen inlet and one combustion gas inlet (e.g. combustion air,
synthetic air)
The gas lines are typically PTFE tubes that are fastened to the cabinet wall with a PVDF
screwed gland. Due to the need for leak-tightness and the high temperature load,
stainless steel tubing with a stainless steel fitting (SS316) is provided for hydrogen lines.
