2.4.2 Connecting External Filters to the Sampling Tubes
The external filters, comprising filter, LumaSense accessory number
DS2306, and fitting, LumaSense accessory number UD5041 (optional
accessories), protect the 1309’s sampling airways from airborne parti-
cles such as dust, thus helping to prevent blockage of the airways.
The filter unit is attached to the tubing as follows (see Fig.2.9):
Fig.2.9 Attaching Fitting UD5041 and Filter DS2306 to sampling tubing

2.4.3 Connecting a Water-trap Filter
The In-line Genie Membrane Separator (LumaSense order no. UA1365)
avoids condensation in the sampling and measuring instruments. Use
the filter in the immediate environment of the instrument so it main-
tains either the same temperature, or a lower temperature than the in-
struments.
