7. PROBES
Metal Gooseneck Probe
The metal gooseneck probe (Part No. GP-514) is a 14 inch long flexible probe which
connects to the dust and water-block filter and has a quick connect fitting.
Standard Probe
The standard probe (Part No. SP-306), a rigid tube, connects to the dust and water-block
filter. If extra length is desired, an extension (7”, SP-308) is screwed finger-tight onto the end of
the probe. A rubber gas collector (Part No. RT-107) is useful for finding leaks under windy
conditions.
Flue Gas Probe
The flue gas probe (Part No. FP-110) is a telescoping metal probe screwed finger-tight into
the flue gas filter. The other end of the filter attaches to the dust and water-block filter. This probe,
together with its filter, may also be used for CO measurements in ambient air.
Bar Hole Probes
There are five optional probes suitable for bar holing:
Bar Hole/Ceiling Probe (Part No. BP-034) 34" long, clear, one hole at end.
Bar Hole Probe (Part No. BP-134) 34" long, clear, side holes.
Bar Hole Probe (Part No. BP-136) 36” long, fiberglass, one hole at end.
Bar Hole Probe (Part No. BP-236) 36" long, fiberglass, side holes
Bar Hole Probe (Part No. BP-536) 36" long, steel, side holes.
The bar hole/ceiling probe has a single inlet on the end and comes with a rubber gas
collector (Part No. RT-030) useful for finding leaks in overhead pipes. The stainless steel probe
has an electrically insulated handle. Bar hole probes are designed to be attached to the water block
filter on the hose. A convenient way to release water from a bar hole probe is with a water-stopper
(Part No. WS-001) described in Section 8.
CAUTION: Never attach the flue gas filter cartridge directly to the sample hose - always use
a dust and water-block filter.
WARNING: Hold the probe without touching metal while it is in the flue and immediately
afterwards. Running the instrument in air after a measurement will help
cool the probe quickly and dry the filters.
WARNING : Hold the steel bar hole probe only by the insulated handle to avoid
electrical shock from buried power lines.
CAUTION: Do not use this probe for flue gas measurements. The plastic probe may become
soft, deform or decompose.
