NDIR TYPE INFRARED GAS ANALYZER
(5-COMPONENT ANALYZER)
DATA SHEET
ZKJ
This gas analyzer (ZKJ) is capable of measuring the con-
centrations of NO, SO2, CO2, CO, CH4, N2O and O2 com-
ponents in sample gas.
NO, SO2, CO2, CO, CH4 and N2O are measured by non-
dispersion infrared method (NDIR), while O2 is measured
by built-in type paramagnetic method sensor or external-
mount type zirconia method sensor. A maximum of 5
components including O2 (max. 4 components except for
O2 measurement) are simultaneously measurable.
The mass flow type twin detector of high sensitivity and
reliability adopted in the infrared ray method detection
block makes the measurement hardly affected by interfer-
ing components.
In addition, a microprocessor is built in and a large-size
liquid crystal display is equipped for easier operation,
higher accuracy and more functions.
Optimum as an analyzer unit of measurement system
for combustion exhaust gas from refuse incinerator and
boiler, or gas from different industrial furnaces.
FEATURES
1. Measure five components including O2 simultaneously
and continuously
Simultaneously and continuously measures up to four
components out of NO, SO2, CO, CO2, CH4 and N2O,
plus O2, or up to totally five components.
2. Hardly affected by interference by other gases
The mass flow type twin detector of high sensitivity
and reliability adopted makes the measurement hardly
affected by interfering components, ensuring a stable
operation.
3. Equipped with abundant functions
O2 conversion, average value computation, automatic
calibration, one touch calibration, upper/lower limit
alarm, remote measurement range changeover, range
identification signal output, etc. incorporated can
configure applications to match particular uses.
4. Easy-to-see large LCD unit
The large LCD unit adopted allows observing easily
the indication of all measured components and
computation values.
The interactive operation facilitates setting.
5. 19 inch rack mount structure
The mainframe unitized to 19 inch rack t ype and
electrical signal input/output terminal unit also unitized
easily configure a gas analyzer system.
6. Maximum range ratio is 1 to 25
Measuring ranges are changeable.
7. Drift +/-1% FS/week (more than 0 to 200ppm range)

• Max. 5 components measurement including O2.
• Measuring range ratio ≤ 1:5 (O2)

≤ 1:25

(except for O2)
• Measuring ranges are changeable between
the specified minimum and maximum range
Settable one range or two ranges
• When only N2O analyzer is used, make sure
not to contain any components other than
N2O.
Multicomponent analyzers including N2O
analyzer + CO2 analyzer are used for sludge
incineration. In this case, the range of N2O is
0 to 200ppm/500ppm, and the range of CO2
is 0 to 10%/20%.
*For measurable components and possible combinations
of measuring ranges, refer to Tables 1-(1) to (3).
