1. OVERVIEW
The Model 7500 infrared gas analyzer measures the concentrations of CO2, CO, CH4, SO2 and O2
contained in sample gas. CO2, CO, CH4 and SO2 are measured by non-dispersion infrared method,
while O2 is measured by paramagnetic method. A maximum of 4 components including O2 (a maximum
of 3 components for other than O2 measurement) are simultaneously measurable.
A high-sensitivity mass ow 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.
