Sample Hose & 10 Inch Probe
A 10 foot sample hose and a 10 inch probe are included as standard
with the GX-2003. When desired, the rubber nozzle may be removed
and the sample hose and 10 inch probe may be connected to the inlet
fitting. Sample hose lengths are available from 10 feet to 40 feet (see
“Parts List” on page 78). The quick connect end of the sample hose
connects to the inlet fitting of the GX-2003 and the probe screws onto
the end of the hose with the threaded fitting.
CAUTION: Sample hose lengths of more than 40 feet are not recommended
for the GX-2003 because of flow rate reduction.

Bar Hole Probe (Optional)
An optional bar hole probe is available for the GX-2003. It is designed
to be used when the GX-2003 is operated in Bar Hole Mode to check
bar holes when tracking down underground gas pipe leaks (see
“Chapter 4: Using the GX-2003 in Bar Hole Mode” on page 39). The
bar hole probe has the same handle as the standard probe, but has a 30
inch fiberglass tube instead of the standard tube. Four holes are
drilled through the 30 inch tube’s wall near the end and the end is
plugged so that debris from the barhole cannot be drawn into the
tube. The sample is drawn through the drilled holes in the tube wall.
