Gas Line Connections for the T400 Analyzer – Basic Configuration 
 
For the Model T400 photometric ozone analyzer in its basic configuration (i.e. without 
the optional internal zero air source or valves), attach the following pneumatic lines: 
SAMPLE GAS SOURCE: 
Attach a sample inlet line to the sample inlet fitting.   
  Sample Gas pressure must equal ambient atmospheric pressure (1.0 psig) 
  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:   
  At least 0.2m long 
  No more than 2m long 
  Vented outside the shelter or immediate area surrounding the instrument 
CAL GAS & ZERO AIR SOURCES: 
The source of calibration gas is also attached to the SAMPLE inlet, but only when a 
calibration operation is actually being performed. 
EXHAUST OUTLET: 
Attach an exhaust line to the EXHAUST outlet fitting. 
  The exhaust line should be a maximum of 10 meters of ¼” PTEF tubing.  
 
Once the appropriate pneumatic connections have been made, check all pneumatic 
fittings for leaks using the procedures defined in Section 11.3.4.
