NDIRTYPE INFRARED GAS ANALYZER
(3-COMPONENT ANALYZER)
DATA SHEET
ZKJ7
This product is the replacement of our gas analyzer <model: ZRG>
This gas analyzer (ZKJ7) is capable of measuring the con-
centrations of NO, SO2, CO2, CO, CH4 and O2 components
in sample gas.
NO, SO2, CO2, CO, CH4 are measured by non-dispersion
infrared method (NDIR), while O2 is measured by external-
mount type zirconia method sensor. A maximum of three
components including O2 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 gas measurement system
for combustion exhaust gas from refuse incinerator and
boiler, or gas from different industrial furnaces.
Combination of this product and model sampling system
(ZSU) is satisfied authentication test by measurement act.

Auto calibration remote start:
Standard Functions
Output signal holding:
Output signals are held during manual
Auto calibration is carried out only once
according to an external input signal.
Calibration sequence is settable in the
same way as the general auto calibra-
tion.
Auto calibration is started by opening
the auto calibration remote start input
terminals after short-circuiting for 1.5
seconds or longer.
and auto calibrations by activation of
holding (turning “ON” its setting).
The values to be held are the ones just
before start calibration mode or setting
value.
It is selectable.
Indication of instantaneous values will
not be held.
Remote output holding:
Auto zero calibration:
Output signal is held at the latest value
or setting value by short-circuiting the
remote output holding input terminals.
Holding is maintained while the termi-
nals are short-circuited. Indication of
instantaneous values will not be held.
Auto zero calibration is carried out peri-
odically at the preset cycle.
This cycle is independent on “Auto cali-
bradion” cycle.
When zero calibration gas and solenoid
valve for opening/closing the calibration
gas flow line are prepared externally
by the customer, zero calibration will
be carried out with the solenoid valve
drive contact for zero calibration turned
on/off at the set auto zero calibration
timing.
Switch ranges :
The switch ranges is available in manu-
al, auto, and remote modes. Only pre-
set switch method is effective.
Allows range to switch by key operation.
Allows range to switch from low to high
range when 90%FS or more is available
in the low range.
Manual:
Auto:
Auto zero calibration cycle setting:
Auto zero calibration cycle is set.
Setting is variable within 1 to 99
hours (in increments of 1 hour) or
Setting is variable within 1 to 40 days
(in increments of 1 day)
Allows range to switch from high to
low range when 80%FS or less is avail-
able in the low range.
Remote:
No-voltage contact input (for measur-
able components)
Gas flow time setting:
Allows range to switch via an external
signal when remote range switch input
is received.
When the contact input terminals for
each component are short-circuited,
the first range is selected, and it is
switched to the second range when the
terminals are open.
The timing for flowing zero gas in
auto zero calibration is set.
Settable 60 to 900 seconds (in incre-
ments of 1 second)
High/Low limit alarm:
Alarm contact output turns on when
measurement value reach to the preset
high or low limit alarm value.
Contacts close when the channel value
of each channel becomes larger than
the high alarm limit value or smaller
than the low alarm limit value.
Range identification signal:
The present measuring range is identi-
fied by a contact signal.
The contact output terminals for each
component are short-circuited when
the first range is selected, and when
the second range is selected, the ter-
minals are open.
Instrument error contact output:
Contacts close at occurrence of ana-
lyzer error No. 1, 3 or 10.
Calibration error contact output:
Auto calibration:
Contacts close at occurrence of manual
or auto calibration error (any of errors
No. 4 to 9).
Auto calibration is carried out periodi-
cally at the preset cycle.
When a standard gas cylinder for
calibration and a solenoid valve for
opening/closing the gas flow line are
prepared externally by the customer,
calibration will be carried out with the
solenoid valve drive contacts for zero
calibration and each span calibration
turned on/off sequentially at the set
auto calibration timing.
Auto calibration status contact outputs:
Contacts close during auto calibration.
Pump ON/OFF contact output:
During measurement, this contact
close. While calibration gas is flowing,
this contact open. This contact is con-
nected in power supply of pump, and
stop the sample gas while calibration
gas flowing.
Auto calibration cycle setting:
Auto calibration cycle is set.
Average value reset:
Average value after O2 conversion
is started under preset condition by
opening the average value reset input
terminals after short-circuiting for 1.5
seconds or longer.
Setting is variable within 1 to 99 hours (in
increments of 1 hour) or 1 to 40 days (in
increments of 1 day).
Gas flow time setting:
The time for flowing each calibration
gas in auto calibration is set.
Reset is carried out by short-circuiting.
Restart is carried out by opening.

Note 9 Precaution to observe when performing installation of two analyzers with external O2 analyzer
• When two ZKJ7 are lined up side by side and installed with external O2 analyzer, Be sure to observe connection of external O2
analyzer shown following diagram on the right side. (with converted value/converted average value)
In this case O2 indication can not be conducted with second ZKJ7 (due to limitation of measurement )
Please refer to "Connecting method/analog output component" for connection to the terminal.

• O2 range is fixed 0-25%.
• With these connection component for second analyzer should be NO sensor, SO2 sensor or NO/SO2 sensor.
Please refer to the "correspondence table for measured value" "Code symbols" for details.
• When ZRG is replaced, two analyzers should be replaced at the same time.

CODE SYMBOLS
Remark: The Zirconia system, due to its
principle, may produce a measuring
error due to relative concentration
versus the com-bustible O2 gas
concentration. Also, a corrosive gas
(SO2 of 250 ppm or more, etc.) may
affect the life of the sensor.
