2.4 Connecting Tubing to the 1309
The 1309 is connected via tubing to:
the sampling points;
to the gas-monitor being used to analyse the gases that are sam-
pled;
to the external pump.
Note: the performance of the 1309’s sampling system is dependant on
the type of external pump used and the length and diameter of the
sampling tubing.
Sampler tubing for use with the 1309 is available from LumaSense:
polytetrafluoroethylene (PTFE), 50m roll, accessory number AF0614.
Using this tubing material minimizes the risk of gases being adsorbed
onto the tube’s surface, which would result in inaccurate measure-
ments.
WARNING! Avoid water condensation in the instrument.
Liquids must be prevented from entering the instrument. It is therefore
important that warm humid gases are not drawn into a cold instrument
because condensation will take place. If such a situation is likely to oc-
cur, you must ensure that the gases are drawn through water-trap fil-
ters before they enter the sampler channels of the 1309. This will re-
move the water vapour in the gases and thus prevent condensation
within the instrument. Use the water-trap filter in the immediate envi-
