Introduction
Fuji Electrics NDIR (Non-Dispersion Infrared
Ray) gas analyzers have been widely used in many
applications. The dual beam infrared gas
analyzer models ZRF ZRG can be incorporated
with a zirconia oxygen sensor to measure oxygen.
And with an internal microprocessor increases
functionality, improves operationally and easy
maintenance. And single beam infrared gas
analyzer model ZRH which has simple structure,
economical and easy maintenance has added joy to
the family.

I) Why use infrared analyzer for emission
monitoring?
Total production of SO2 NOx analyzers in
Japan in 1997 that is approved by JQA are 917
sets.

I) Why use infrared analyzer for emission
monitoring?

• Both SO2 and NOx can be measured
• Easy maintenance
• Most cost effective
• CLD
• Expensive
• Difficult maintenance
• UV
• Expensive
• Short life (Light source approximately 6 months)

II) What is unique about Fujis gas analyzers?

• Various products line-up
• ZRH CO, CO2, CH4 SO2
• Simple Structure Minimum Maintenance
• ZRF CO, CO2, NOx, SO2 CH4 ( O2)
• High Performance 19 Rack Mounting
• ZRG CO, CO2, NOx, SO2 CH4 ( O2)
• High Performance Wide Range, (CO 0-2ppm)
• ZFP9 CO2 Controller
• Simple Air Monitoring

II) What is unique about Fujis gas analyzers?
NDIR Non-Dispersion Infrared Ray Gases have
different kind of infrared absorption and by
utilizing the wavelength corresponds to the
waveband, we are able to determine the amount
infrared ray being absorbed by the gases and we
are able to tell the concentration. Internal
pressure in the left detector will be higher than
one in the right detector. And by blocking the
ray, the pressure in both detectors will be
equalized the changing volume of absorbing
infrared ray is detected.

II) What is unique about Fujis gas analyzers?

• 1) Mass Flow Sensor Offers
• Excellent Linearity 1 FS
• High Rangeability 20 to 1
• Against Condenser Microphone (10 to 1)
• Less Effect By Vibration
• No Moving Mechanical Parts

II) What is unique about Fujis gas analyzers?
Mass Flow Sensor Condenser Microphone
Basic Principle Resistance Measurement (Detecting temperature by pressure change) Basic Principle Capacitance Measurement (Detecting pressure change)
No moving parts High sensitivity sensor introduces good linearity Gas impurities in detector which will result interference can be removed by making full vacuum condition Mechanical moving parts Low sensitivity sensor introduces poor linearity Gas impurities in detector which will result interference cannot be removed as full vacuum condition are not possible

2) Single light source provides- Long Term
Stability 0.5 to 2 FS/week (Other
suppliers show the stability for one day only)
Against dual light source ? Both sources
cannot be exactly same ? It creates error in
measurement
Our test data of span drift for 28 days Less
than 1FS (97.1ppm SO2/N2)

II) What is unique about Fujis gas analyzers?
Butterfly wing sector

• 3) Single Point Chopper
• with Fujis peculiar rotary sector provides
• Repeatability 0.2 to 0.5 FS
• because of excellent S/N ratio against
  conventional
• double point chopper

II) What is unique about Fujis gas analyzers?

• 4) Interference Compensating Detector Eliminates
• Interference of Moisture
• Cross sensitivity to moisture Less than 2 ppm
  
• at 2? of saturated H2O
• ? Twin detector (Main detector IC Detector)
• result in excellent compensation.
