Model SG750 Stack Gas Analyzer

GS 11G04G01-01E

GENERAL
The SG750 Stack Gas Analyzer consists of an infrared gas analyzer, a zirconia oxygen analyzer, and a
sampling unit.
The SG750 can simultaneously measure up to ve
components: sulfur dioxide (SO2), nitrogen oxides
(NOX), carbon monoxide (CO), carbon dioxide (CO2)
and oxygen (O2).

FEATURES
1. Simultaneously measures up to ve gas components
The SG750 uses a combination of an infrared gas
analyzer(s) and a dedicated zirconia or paramagnetic oxygen analyzer to simultaneously determine
concentrations of up to ve gas components - NOX,
SO2, CO, CO2 and O2.
2. Minimizes the effects of interference from other gas
components
The use of interference compensation in the analyzer virtually eliminates the effects of interference
from other gas components.
3.Maintenance can be performed from front side, thus
saving the installation space. Unitized structure
of the analyzing block and gas sampling module
enables better maintenance.

4. Provides a wealth of functions
The SG750 provides a variety of standard functions,
including reliability-enhancing self-diagnosis, auto
matic calibration, correction to O2 values, averaging,
high and low limit alarms, and more.
5. Wide dynamic range
The SG750 is highly sensitive with a wide dynamic
range which can be switched up to 1:25 and which
can be changed arbitrarily.

SAMPLING SYSTEM CONFIGURATION
