Notes:
1/8 NPT female thread (stainless steel 1.4305/SAE 303)
Connection of flexible tubes: straight screwed fittings (PP) with nozzles for flexible
tubes with inside diameter = 4 mm (supplied)
Connection of pipelines: Threaded connections (not supplied)
If the internal gas lines are flexible tubes, the pressure sensor (standard) and the
oxygen sensor (option) are internally connected as follows:
in the outlet of sample cell 1 for a sample cell and two separate feed paths
in the outlet of sample cell 2 with two sample cells in series.
If the internal gas lines are stain steel pipes, the oxygen sensor and the version
with separate gas feed paths are not possible.
