| PTFE intake 4.5 m long with an internal diameter 0.04 m. Intake height: 7 metres above ground. The intake is connected to a glass manifold approximately 1.40 meters long. The manifold consists eight nipples to feed trace gases instruments. The flow rate through the complete inlet is supported by a blower. Ambient air is supplied to the analysers via 6mm PTFE tube connected between the manifold and the inlet of the analyser. The analyser is assigned with a 5 micron filter which is changed every two weeks. | |
