1.5 Description of the Main Unit
Teledyne's Series 7600 Infrared Gas Analyzer measures the
concentration of NO, SO
2
, CO
2
, CO, and CH
4
in a gas mixture on a
continuous basis. The Series 7600 can also be supplied with an oxygen
sensor, which allows the simultaneous measurement of oxygen
concentration as well. The NEMA-4 enclosure can be X or Z-purged to
satisfy hazardous area installation requirements.
The system uses a high-sensitivity mass flow type twin detector for
infrared measurements. A single beam, double path optical bench is
installed in conjunction with a serial dual-layer transmission detector.
The concentration of the desired gases is displayed on a large, easy-
to-read backlit LCD. The user interface is very intuitive and the menu /
mode selection buttons, which are readily accessible, provide the
operator with dynamic control and extensive diagnostic capabilities. See
Figure 1-2.
The front panel mounted power switch turns the instrument on and
off while the display switch controls power to the display.
Front panel mounted handles make sliding the instrument out of the
panel rack or enclosure a simple task for easy maintenance.
