NOTE: Response time increases with the length of the sample hose.
Long sample hoses will require more time to show a response
at the Gas Tracer. The maximum sample hose length
recommended for the Gas Tracer is 50 feet. Consult RKI

Using Optional Probes and Fittings
This section describes how to use the 8 meter hose with floating head and the
purge tee fitting.
Using the 8 Meter Hose with Floating Head
This probe is designed to be used in a tank or a well that may have water or
some other liquid at the bottom. To use the 8 meter hose with floating probe:
1. Start up the Gas Tracer as described in “Start Up, Normal Mode”
on page 20.
2. Connect the 8 meter hose with floating probe to the Gas Tracer’s
quick connect inlet fitting.
3. Slowly lower the probe into the area you wish to monitor. If the
probe hits water, it will float and continue to monitor the area.
