Figure 3-24: Gas Line Connection w/Ambient Zero/Pressurized Span Valves (OPT 50B)

SAMPLE GAS SOURCE

Attach a sample inlet line to the SAMPLE inlet fitting.

∙Use PTFE tubing; minimum O.D ¼”.

∙Sample Gas pressure must equal ambient atmospheric pressure (29.92 in-Hg).

∙In applications where the sample gas is received from a pressurized manifold, a vent must be placed on the sample gas line. This vent line must be:

∙No more than 10 meters long.

∙Vented outside the shelter or immediate area surrounding the instrument.

CALIBRATION GAS SOURCES

SPAN GAS Attach a gas line from the pressurized source of calibration gas (e.g. a bottle of NISTSRM gas) to the SPAN1 inlet.. Use PTFE tubing; minimum O.D ¼”.

ZERO AIR (the dual-stage zero Air Scrubber makes zero air)

VENTING

Attach a line to the SPAN2/VENT outlet. It should be:

∙¼” PTFE tubing.
