OURCE
Attach a sample inlet line to the SAMPLE inlet port. The sample input line should not
be more than 2 meters long.
•
Maximum pressure of any gas at the sample inlet should not exceed 1.5 in-hg above
ambient pressure and ideally should equal ambient atmospheric pressure.
•
In applications where the sample gas is received from a pressurized manifold, a
vent must be placed on the sample gas before it enters the analyzer.

OURCES
The source of calibration gas is also attached to the SAMPLE inlet, but only when a
calibration operation is actually being performed.
Note Zero air and span gas inlets should supply their respective gases in
excess of the 800 cc3/min demand of the analyzer.

ENTING
The span gas, zero air supply and sample gas line MUST be vented in order to ensure
that the gases input do not exceed the maximum inlet pressure of the analyzer as well as
to prevent back diffusion and pressure effects. These vents should be:
•
At least 0.2m long;
•
No more than 2m long and;
•
Vented outside the shelter or immediate area surrounding the instrument.

UTLET
Attach an exhaust line to the analyzer’s EXHAUST outlet fitting. The exhaust line
should be:
•
PTEF tubing; minimum O.D ¼”;
•
A maximum of 10 meters long;
•
Vented outside the T300/T300M Analyzer’s enclosure.
