NDIR TYPE INFRARED GAS ANALYZER
DATA SHEET
ZRG
This NDIR gas analyzer features 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.
This analyzer is used not only for measuring environmental pollution but is also used for various processes and/or
experiments.
This product, combined with sampling system (ZSP), has
passed the type-approval test based on Weight and Measure Act.
FEATURES
(1) Use of a microprocessor provides high accuracy, multiple functions and easy operation.
• A maximum of 3 gas components can be calibrated
with the built-in automatic calibrator (option).
• Using a signal from a zirconiz O2 sensor (ZFK3) or from
any other O2 sensor, the gas analyzer is able to output a value converted into O2 (option).
• Alarm function to emit high/low limit contact output
is also available (option).
• Measuring range can be selected by using external
single (option).
• Zero and span can be calibrated with high accuracy,
simply by pressing calibration keys.
• A self-diagnosis function is included.
(2) This analyzer utilizes mass flow detector featuring high
sensitivity and reliability. It has 2 standard measuring
ranges with a range ratio of up to 1:20.
(3) Three different gas components can be measured simultaneously by connecting a zirconia O2 sensor (ZFK3),
in addition to one-and two-component type sensors.
(4) Besides the standard measurement type, a sample switching type and a differential flow type are also available.

O2 correction output:
An private O2 sensor is used for correcting the measured gas concentration into
the value at standard O2 concentration.
For obtaining the NOx exhaust standard
value, NOx concentration and residual
oxygen concentration in exhaust gas are
measured simultaneously, then it is corrected according to the following equation. (Application of this equation is mandatory for the NOx exhaust standard.)
C= 21 – On

Description of sample switching system
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 effect of interfering components plus zero
drift.
