• It is recommended that a stainless steel of Teflon (Trademark of
the DuPont Company) sample line be used for monitoring gases
that are highly reactive such as:
• Nitrogen Dioxide
• Sulfur Dioxide
• Chlorine
• Chlorine Dioxide
• Hydrogen Chloride
• Ammonia
• Fluorine
• Bromine.
• Use an end-of-line filter (P/N 637921) with the above gases.
The filter and sample line should be inspected periodically and
replaced if dirty.
All Ultima X Gas Monitors must be mounted in ambient,
interference-free air; otherwise, erroneous readings may
result.
Do not attempt to clean the sample line by applying com-
pressed air.
1. Remove all protective packaging plugs and/or caps from the
Aspirated Sampling Module:
• gas inlet
• exhaust ports.
2. Attach a 1/4-inch (6.35 mm) OD sample tubing to the flow block
sample inlet fitting on the Ultima X Gas monitor (FIGURE 1-1).
Ensure tubing is compatible with the sampled gas.
3. Route the sample tubing to the area to be monitored.
NOTE: Do not run the sample tubing in water or across areas of
vibration, doorways, man ways or access ways; otherwise,
a sample tubing leak or tripping hazard may result.
4. Using suitable hardware (not supplied):
• fasten the sample tubing to supports
• fasten the end of the sample tubing and sample inlet in the
monitoring area.
• The sample inlet should be pointed downward to prevent
dirt and water from entering the sample tubing line.
