MICROPROCESSOR BASED
NDIR GAS ANALYZER
DATA SHEET
ZRF
This NDIR gas analyzer features a high accuracy, multiple
functions and easy operation through use of a microprocessor.
It also utilizes a mass flow detector noted for its high sensitivity
and reliability. Being housed in a 19 inch rack case suitable
for mounting on a panel or a table top, this analyzer is applicable
not only for measurement of environmental pollution but for
use in various processes and/or experimental laboratories.
FEATURES
(1) Use of a microprocessor provides high accuracy,
multiple functions and easy operation.
• The built-in automatic calibrating function allows
calibration of up to three components (option).
• The signal from a zirconia O 2 sensor (ZFK3) or
other O2 meter enables output of an O2 correction
value (option).
• Includes an alarm function providing an upper/
lower limit contact output (option).
• Range can be changed over by external signal
(option).
• Zero and span calibration is accurate and easy by
means of operating keys.
• A self-diagnosis function is included.
RS232C port available (option).
(2) This analyzer utilizes a mass flow detector featuring
high sensitivity and reliability. It is equipped with
two standard ranges for a range ratio of up to 1:20.
(3) Addition of a zirconia O 2 sensor (ZFK3) to the one/
two-component analyzer allows measurement of up
to three components simultaneously.
(4) Besides the standard method of measurement, a
sample switching system and differential flow
system are also available.

Optional specifications
(These are added on request. Refer to the "Code symbols".)
Filter, flow checker:
Membrane filter and flow checker are
built in.
Remark: The built-in membrane filter is a glassfiber paper monitoring type. The prefilter should be prepared separately.
Pump:
A small two-throw electromagnetic pump
is built in, so sample gas and reference
gas can be sampled separately at the
same time.
CO/CO 2 converter (emission level calculation):
This converter uses a special catalyst for
converting efficiently into CO 2 the CO
contained in sample gas which is used
in the sample switching type etc. The
converter is built in the analyzer.
O2 correction output (emission levels calculation):
An exclusive O 2 sensor is used for correcting the measured gas concentration
into the value at standard O2 concentration.
For obtaining the NOx and/or SO 2 exhaust standard value, ZRF can measure
the NOx and/or SO2 concentration and
simultaneously the residual oxygen concentration in exhaust gas, and then correct according to the following equation.
(Application of this equation is mandatory
for the NOx or SO2 exhaust standard.)

In case of carbon monoxide measurement, a high performance converter is provided to convert carbon monoxide into
carbon dioxide. Here, the carbon monoxide is eliminated
and the gas is led into one cell of the high-sensitivity infrared
analyzer. In the othe flow path, the gas is led directly into
the other cell of the analyzer. The output of analyzer varies
with the difference of the concentration of the carbon
monoxide between two cells, eliminating the effects of
interfering components.
Moreover, zero calibration can be held without zero standard gas, flowing the same reference gas into both reference and sample cell by activating changeover valve.
The measured gas is divided into two, and in one of the
flow paths, a high-performance converter is provided to
convert carbon monoxide into carbonic acid gas. Here,
the carbon monoxide in the measured gas is eliminated
and the gas is led into one cell of the high-sensitivity infrared
analyzer. In the other flow path, the gas is led directly into
the other cell of the analyzer.
These flow paths are changed over via changeover valves
SV1 and SV2 every 50 seconds by means of the changeover
valve drive signal transmitted from the analyzer. By carrying
out this changeover cyclically, the output of the analyzer
varies with the concentration of the carbon monoxide in
the measured gas. Use of the obtained variation width as
a measured value enables improving the S/N ratio and eliminating the effects of interfering components plus zero drift.

For O2 correction, the gas analyzer ZRF can accept linealized
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 O 2 sensor Model ZFK3.

Linearity:
Within ± 2% of full scale

Response time: Approx. 20 seconds (for 90% response)
Measured gas flow rate:
0.5 ± 0.25r/min
Remark: The Zirconia system, due to its principle,
may produce a measuring error due to
relative concentration versus the combustible O 2 gas concentration. Also, a
corrosive gas (SO2 of 250 ppm or more,
etc.) may affect the life of the sensor.
