interruption of sampling and a low flow alarm if the probe tip is
blocked.
• 30 inch stainless steel probe
Figure 8: 30 Inch Stainless Steel Probe
This probe is physically the same as the 30 inch aluminum probe
and is intended for applications where a high level of corrosion
resistance is required in the long probe tube.
• Barhole probe
Figure 9: Barhole Probe
An optional bar hole probe is available for the Gas Tracer. It is
designed to be used when the Gas Tracer is operated in Bar Hole
Mode to check bar holes when tracking down underground gas
pipe leaks (see “Chapter 4: Using the Gas Tracer in Bar Hole Mode”
on page 91). 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.
• 32 inch telescoping probe with dust filter
Figure 10: 32 Inch Telescoping Probe with Dust Filter
This probe is designed for use where it is necessary to put the
probe tip in areas not accessible with the 10 inch probe with dust
filter and applications where the probe tube must be collapsible for
storage.
