Optional Probes
Various optional probes designed for specific applications are available for
the GX-2012. They include the following:
• 30 inch aluminum probe
Figure 7: 30 Inch Aluminum Probe
This probe is designed for applications where it is necessary to put the
probe tip in areas that are out of reach with the standard probe. A small
breather hole near the end of the probe tube prevents 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 GX-2012. It is designed to
be used when the GX-2012 is operated in Bar Hole Mode to check bar
holes when tracking down underground gas pipe leaks (see “Chapter 4:
Using the GX-2012 in Bar Hole Mode” on page 73). 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.
