NDIR TYPE INFRARED GAS ANALYZER
(3-COMPONENT ANALYZER)
DATA SHEET
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.

FEATURES
1. M e a s u r e t h r e e c o m p o n e n t s i n c l u d i n g O ₂
simultaneously and continuously
Simultaneously and continuously measures up to three
components out of NO, SO₂, CO₂, CO, CH₄, plus O₂, or
up to totally three components.
2. Hardly affected by interference by other gases
The mass flow type twin detector of high sensitivity
and reliability adopted makes the measurement hardly
affected by interfering components of other gas,
ensuring a stable operation.
3. Equipped with abundant functions
O₂ conversion, average value computation, automatic
calibration, one touch calibration, upper/lower limit
alarm, remote measurement range changeover, range
identification signal output, etc. incorporated can
configure applications to match particular uses.
4. Easy-to-see large LCD unit
The large LCD unit adopted allows observing easily
the indication of all measured components and
computation values.
The interactive operation facilitates setting.
5. Maximum range ratio is 1:25
Measuring ranges are changeable.
6. Drift +/-1% FS/week (more than 0 to 200ppm range)
