The infrared gas analyzer (IR200) measures the concentrations of CO
2
, CO, CH
4
, SO
2
, NO and O
2
contained in sample gas.
CO
2
, CO, CH
4
, SO
2
, and NO are measured by non-dispersion infrared method, while O
2
is measured by
paramagnetic or fuel cell method. Up to 4 components including O
2
(3 at the maximum for measurement
of components other than O
2
) can be measured simultaneously.
A high-sensitivity mass flow sensor is used in the detector unit of infrared method. Due to use of single
beam system for measurement, maintenance is easy and an excellent stability is ensured for a long period
of time.
In addition, a microprocessor is built in and a large sized liquid crystal display is provided for easier
operation, higher accuracy and more functions.
This analyzer is thus optimum for combustion control of various industrial furnaces, botanical study and
global atmospheric research.
