INFRARED GAS ANALYZER

DATA SHEET ZRJ

This gas analyzer (ZRJ) is capable of measuring the
concentrations of CO2, CO, CH4,SO2, NO and O2 components
in sample gas.
CO2, CO, CH4, NO, and SO2 are measured by non-dispersion
infrared method (NDIR), while O2 is measured by paramagnetic,
fuel cell, or zirconia method. Up to 4 components including O2 (up
to 3 components in measurement of gases other than O2) can
be measured simultaneously.
A high-sensitivity mass flow sensor is adopted in the
detection block for the infrared method. Due to use of single
beam system for measurement, maintenance is easy and an
excellent stability is ensured for a long period of time.
In addition, a microprocessor is built in and a large-size
liquid crystal display is equipped for easier operation,
higher accuracy and more functions.
This analyzer is thus optimum for combustion control of
various industrial furnaces, botanical study and global
atmospheric research.

<Code specification for ordering>

(1) Code symbols should be specified.
(2) Range combination should be the one allowed in separate tables.
(note1) When only O2 measurement is necessary, “Y”should be specified at the 5th digit.
In this case, specify O2 measuring range at 17th 18th digits.
(note2) When “B” is specified at the 6th digit, O2 sensor signal has to be set as 0-1V DC linear corresponding to full
scale.
External Zirconia O2 sensor and external O2 analyzer are not included in the scope of supply, and has to be
separately ordered..
(note3) Rated voltage and plug type of the attached power cable is different depending on the code “J”, “E” and
“U” in the 10th digit.
Select appropriate code according to operationg power supply voltage in the final destination.
(note4) Refer to Table 1 to 9, for possible combination of measuring components and ranges in the data sheet.
(note5) “C” can be specified at 11th digits, ONLY for CO measurement.
(note6) “E” can be specified at 11th digits, except CH4 measurement.
(note7) O2 correction is calculated only for NO, SO2 and CO.
Both average value output after O2 calculation and O2 average value output are provided at the same time.
Peak count alarm can be added only for CO measurement.
* With the triple-component analyzer for NO, SO2, and CO, the values after correction only are displayed
and output (average of corrected values is not output). If the average value should be output, specify Z,
and separately describe what values should be output. Up to 8 values can be output.
Peak count alarm can be added only for CO measurement.
(note8) When no O2 measurement, “Y” should be specified.
(note9) This analyzer has different calibration curve corresponding to sample gas composition.
When “ B ” or “ Z ” is specified at the 21th digit, the gas composition table should be issued.
“Standard” means N2 balance adjustment.
In case that the measurement unit is specified as “mg/m3 ”, it is necessary to select “unit : mg/m3 ”(Code“C”)
at the 21st digit.
Please refer to the table shown below for the corresponding range code based on “ mg/m3 ”.
(note10) When the 21st code is "B", the range code "X" and "R" are not available.

* Study of table
When CH1 shows SO2, it means that the display and the output of CH1 correspond to the component of SO 2.
The "correct" means O2 correction.
If A or C is selected for the 20th digit of the code symbols, “NOx” is displayed as the component display of “NO.”

19-inch rack mounting method:

The mass of the instrument should be supported at the bottom of the unit (or the side of the unit when mounted with
the slide rails).
Also, for facilitate maintenance, a structure which allows extraction of the main unit by using the slide rail is recom-
mended.
