INFRARED GAS ANALYZER FOR STACK GAS

DATA SHEET

ZSU-5

This analyzer consists of an infrared gas analyzer, an O2 sen-

sor and a gas sampling device. It is used for simultaneous

and continuous measurement of the NOX, SO2, CO, CO2 and

O2 components in the ï¬ue gas of various boilers, garbage

incinerators, etc.

For CO and O2 measurement speciï¬cations, the function for

coping with the Japanese regulation on dioxin emission is

incorporated.

FEATURES

1. Gas concentrations of 5 components is measurable simul-

taneously and continuously

NOx, SO2, CO and CO2 gas concentration measurements

are integrated by infrared method, to which a zirconia or

magnetic type O2 sensor is added for O2 measurement.

Therefore, the gas concentrations of 5 components are

simultaneously and continuously measurable.

2. The use of highly sensitive and reliable mass ï¬ow detec-

tor allows the range ratio of up to 1:25 with the standard 2

range.

3. Maintenance can be performed from the front side, thus

saving the installation space.

Unitized structure of the analyzing block and gas sampling

module enables better maintenance.

4.Provided with abundant functions including O2 correc-

tion output, average value output, automatic calibration,

CO peak count alarm, automatic range changeover, and

alarms.

5.N2O and CH4 can also be measured as an optional feature.

Having warming effect 300 times as high as that of CO2,

N2O is the greenhouse gas most controversial now.
