Design:  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) 
Notes:  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.
