the O-ring compression force.
Charcoal Filter
The charcoal filter is located in the front of the flow chamber next to the CO
sensor. It contains activated charcoal. The CO sensor will respond if exposed
to H
2
S and certain hydrocarbon gases. The charcoal filter scrubs these gases
out of the sample to avoid false CO readings. If false or elevated CO readings
are noticed, especially in the presence of H
2
S, change the charcoal filter. The
charcoal inside the filter cannot be replaced; the entire filter must be
replaced.
Exhaust Fitting
The exhaust fitting is located below the inlet fitting. It routes the gas sample
out of the EAGLE 2. It includes a female 10-32 thread that can be used for
the installation of a hose barb or other type of fitting that has a male 10-32
thread so that the exhaust can be routed to a particular location with flexible
tubing if desired.
Standard Accessories
Standard accessories include the shoulder strap, the sample hose, and the
hydrophobic probe.
Shoulder Strap
A comfortable elastic shoulder strap clips to the EAGLE 2 at the front and
rear of the top case. It clips to stainless steel rings that are installed in features
on the top case. It can be removed from the EAGLE 2 by opening the clip at
each end of the strap and removing it from the strap ring at the front and rear
of the top case.
Hose and Probe
A 5 foot polyurethane sample hose and a 10 inch hydrophobic probe are
included as standard. The hose has a male quick connect fitting on one end
and a female quick connect fitting on the other end. The probe has a male
quick connect fitting. Normally, the male end of sample hose is installed in
the EAGLE 2 inlet fitting and the probe is installed in the female end of the
hose. However, if the sample hose is not needed for monitoring a particular
area, the probe may be installed directly to the inlet fitting. Sample hose
lengths are available from 5 feet (standard length) to 125 feet (see “General
Parts List” on page 84). A teflon lined hose is provided with all units that
contain a PID sensor. This hose must be used when operating a PID EAGLE
2 (see “Appendix D: PID Sensors” on page 136).
