INFRARED GAS ANALYZER
(LOW-CONCENTRATION MEASUREMENT TYPE)
DATA SHEET
ZPG
This gas analyzer (ZPG) is capable of measuring the
concentration of NO, SO2, CO2, CO and O2 components
in sample gas. NO, SO2, CO2, CO are measured by nondispersion infrared method (NDIR), While O 2 is measured
by fuel cell or paramagnetic and zirconia method.
Through use of the sample switching system, ZPG is
capable of canceling drift in zero point of the measurable
component by NDIR.
Optimum use as an analyzer unit of measurement system
for gas separation process and atmospheric environment
measurement and combustion exhaust gas from refuse
incinerator and boiler, or gas from various industrial
furnaces.
FEATURES
1. High sensitivity
Equipped with the newest upgraded mass flow sensor.
It is measurable of 0-5ppm range by newly-designed
measurement unit.
2.Excellent stability
Due to adoption of sample switching method (note1).
It is capable of canceling drift in zero point of measurable component.
3.Easy maintenance
Single beam design simplifies maintenance and minimizes maintenance costs compared with double beam
or similarly equipper GFC based system.
4.Small and light
The size is small 133x483x382mm (HxWxD) and light
(7kg). It is capable to measure one of NO,SO 2,CO2,CO
components by NDIR and measure one of O 2 components by O2 sensor at once.
5.Extensive functions
Various optional functions are available such as auto
calibration control, atmospheric pressure correction, high and low concentration alarm, remote range
switch, and range identification signal,etc.
note1) Excellent long term stability due to sample gas
and relative gas introduced alternately to the
measurement unit.

Standard Functions
Output signal holding:
Output signals are held unchanged during
manual and auto calibrations by activation
of holding (turning “ON” its setting).
The values held are those just before start
calibration mode or setting value.
It is selectable.
Indication of instantaneous values will not
be held.
Switch ranges: The switch ranges function is available in
manual, auto, and remote modes. Only
preset switch method is effective.
Manual: Allows range to switch by key operation.
Auto:
Automatically switched from first range to
second range when the measured value
exceeds to 90%FS of first range.
Automatically switched from second range
to first range when the measured value
drops to 80% or less first range.
Remote: Voltage contact input (for measurable
(Option) components)
Allows range to switch via an external
signal when remote range switch input
is received.
When the contact input terminals for
each component are input voltage, the
first range is selected, and it is switched
to the second range when the terminals
are open.
* These range value are settable between original
first range and second range.
Optional Functions
Remote output holding:
Output signal is held at the last value or
preset value by voltage input the remote
output holding input terminals.
Holding is maintained while the voltage
input the terminals. Indication of instantaneous values are not held.
Range identification signal:
The present measuring range is identified
by a contact position.
The contact output terminals for each
component close when the first range is
selected, and when the second range is
selected, the terminals are open.
Auto calibration:
Auto calibration is carried out periodically
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 cycle setting:
Auto calibration cycle is set.
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.
Settable within 60 to 900 seconds (in
increments of 1 second)
Auto calibration remote start:
Auto calibration starts by opening the auto
calibration remote start input terminal after
short circuiting for 1.5 sec or longer.
Auto calibration starts when contacts
open.
Auto zero calibration:
Auto zero calibration is carried out periodically at the preset cycle.
This cycle is independent on “Auto calibration” 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.
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 1 to 40 days (in
increments of 1 day)
Gas flow time setting:
The timing for flowing zero gas in auto
zero calibration is set.
Settable within 60 to 900 seconds (in
increments of 1 second)
High/low limit alarm:
Alarm contact output turns on when
measurement value reaches the preset
high or low limit alarm value.
Contacts close when the instantaneous
value of each channel exceeds the high
alarm limit value or falls below the low
alarm limit value.
Instrument error contact output:
Contacts turn on at occurrence of analyzer
error No. 1, 2, 3 or 10.
Calibration error contact output:
Contacts turn on at occurrence of manual
or auto calibration error (any of errors No.
4 to 9).
Auto calibration status contact outputs:
Contacts turn on during auto calibration.
O2 correction:
Correction of measured NO, SO2 and CO
gas concentrations into values at reference
O2 concentration.
Correction formula:
C=
21-On
21-Os
× Cs
C :Sample gas concentration after O 2
correction
CS :Measured concentration of sample
gas
OS :Measured O 2 concentration (Limit
setting: 1 to 20% O2)
On :Reference O2 concentration
(value changeable by setting.0 to
19% O2)
Average value after O2 correction and O2 average value
calculation:
The result of O2 correction or instantaneous
O2 value can be output as an average value
over the preset period of time.
Used for averaging is the moving average
method in which sampling is carried out
at intervals of 30 seconds.
(Output is updated every 30 seconds. It is
the average value in the determined period
of time just before the latest updating.)
Averaging time is settable within 1 to 59
minutes (in increments of 1 minute) or 1
to 4 hours (in increments of 1 hour).
Average value resetting:
The above-mentioned output of average
value is started from the initial state by
opening the average value resetting input
terminals after short circuiting for 1.5 sec
or longer.
Output is reset by input voltage and restarted by opening

Explanation of the sample switching method
Sample gas and relative gas are introduced alternately and constantly to the sample cell of the analyzer by Solenoid valve for switching flow (SV1,SV2 )
Solenoid valve SV1 and Solenoid valve SV2 are switched by the signal sending from the analyzer. Analyzer measures each sample gas and each relative gas on proper timing and transform the change of the relative gas and
sample gas as the concentrate value (= gas concentration of the measurable component)and send output signal.
Due to monitoring the change of the relative gas and sample gas all the time, Influence of the interference components and zero drift are eliminated.

The items in the parentheses
may not be available depending on the selected type on
22th digit.
The normal open side (NO) of
digital output is close when
the function is active without
range ID.
In case of range ID, normal
open (NO) side is close with
First range.
The normal close (NC) side is
close with Second range.

ZPG
Exclusive Zirconia O2 Sensor
(to be purchased separately)
Gas inlet/outlet size:
Rc1/4 or NPT1/4
Power supply: Rated voltage
For O2 correction, the gas analyzer ZPG can accept linearized
0 to 1V DC signal coming from analyzer calibrated 0 to 25%
O2 full scale. If the analyzer is not available, Fuji can supply
exclusive Zirconia O2 sensor Model ZFK.
Measuring method:
Zirconia system
Measurable component and measuring range:
Measurable component Range
O 2
Oxygen
0 to 25vol%
Repeatability: Within ± 0.5% of full scale
Linearity:
Within ± 1% of full scale
Zero drift:
Within ± 1% of full scale/week
Span drift:
Within ± 2% of full scale/week
Response time: Approx. 20 seconds (for 90% response)
Measured gas flow rate:
0.5 ± 0.25L / min
Remark:The Zirconia system, due to its principle,
may produce a measuring error due to relative concentration versus the combustible
O2 gas concentration. Also, a corrosive
gas (SO2 of 250 ppm or more, etc.) may
affect the life of the sensor.
