Gas sampling and gas conditioning technology 9-3.5.1-ME
12.1 CONNECTION OF SAMPLE GAS INLET AND SAMPLE GAS OUTLET
The sample gas inlet and outlet are placed at the bottom side of the analyser and have tube con-
nections DN4/6mm.

Connect the sample gas inlet (rear connection) with a corresponding gas conditioning with
e.g. a PTFE hose DN4/6.
A T T E N T I O N Avoid back pressure in the sample gas outlet because an increase of
pressure will distort the oxygen indication.
Do not bend the connection hoses.
