WARNING: To prevent ignition of a hazardous atmosphere, batteries
must only be changed or charged in an area known to be
nonhazardous.
Pump
A diaphragm pump inside the Gas Tracer draws the sample to the
sensors. It can draw sample from as far as 50 feet from the Gas Tracer.
The pump is not user serviceable.
CAUTION: Sample hose lengths of more than 50 feet are not recommended
for the Gas Tracer because of flow rate reduction.
Flow Chamber
The flow chamber is on the back of the Gas Tracer and is held in place
by three phillips screws. The flow chamber seals to the rubber sensor
gasket which seals to the sensor face inside the Gas Tracer and routes
flow from the pump to the sensor to the exhaust port (also a part of
the flow chamber).
Inlet Filter Holder
The filter holder is a clear plastic dome shaped piece on the top of the
case. A male quick connect fitting is located on the inlet filter holder.
This is the Gas Tracer’s inlet fitting. A cotton dust filter is inside the
filter holder. The filter holder may be removed by turning it
counterclockwise and pulling it away from the case. Two flat
membrane disk hydrophobic filters, a wire mesh disk, and a rubber
filter retaining gasket are held in place by the filter holder and are
located in the bottom of the case chamber where the filter holder is
installed.
Standard Accessories
The standard accessories include the tapered rubber nozzle, belt clip,
sample hose, and 10 inch probe.
Tapered Rubber Nozzle
A cone shaped 4 inch long rubber nozzle is included with the Gas
Tracer as standard. It can be installed on the inlet fitting by pushing
the larger end over it. The smaller end can be inserted through a hole
in a wall or some other access to an enclosed area to sample the
environment.
