Model IR100
Universal Infrared Gas Analyzer

GS 11G2L1-01E

GENERAL
Model IR100 is an intelligent universal infrared gas
analyzer for CO2, CO and CH4. The analyzer is easy to
maintain and works steadily over long periods. The
ideal application of this analyzer is continuous
measurement for the control and monitoring of
combustion in various industrial furnaces as well as
continuous measurement for the study of plants.
FEATURES
1) Two available models
The IR100TA and IR100A, dedicated for analysis of
either CO2, CO, or CH4, IR100TB and the IR100B,
dedicated for simultaneous analysis of CO2 and
CO, are available. The minimum measuring range
for each gas is described below.
CO2: 0 to 500 ppm
CO: 0 to 500 ppm
CH4: 0 to 1000 ppm
2) Stable operation over long periods
A special optical system reduces drift, which is
usually caused by dirt on the measurement cell;
therefore, the analyzer operates stably over long
periods.
3) Influenced less by presence of another
interfering gas
A two-layer serial infrared transmission system
minimizes influence by another interfering gas, for
example, the vapor content in the object gas.
4) Easy maintenance
Maintenance of this instrument is easy since the
analyzer can be easily separated into several basic
units. Optical balance adjustment is also
unnecessary.

5) Wide variety of additional functions
a) Self-diagnosis: indicates error code to notify the
operato of an abnormality.
b) Simple calibration: allows the operator to perform
zero- and span-calibration by only pressing the
calibration key while the reference gas is flowing.
*c) Automatic calibration: automatically performs zeroand span-calibrations periodically at predefined
intervals.This function can calibrate CO2 and CO
simultaneously.
*d) Remote switching of the measuring range: allows
a range to be switched to another range by
transmitting signals from a distance. This function
is available for each gas.
*e) Range identification: outputs contact signals to
identify the range which is being selected. These
signals are output for each gas.
Note: The functions marked with an asterisk (*) are
optional.
