Infrared Gas Analysers

Infrared Gas Analysers
Fuji Electric

Fuji Electric Extractive Gas Analyzers for process control and continuous measurement of stack emissions.

Their QAL1 certification guarantees high performance and regulatory and normative compliance.

Reliable and precise, their design quality guarantees 24-hour operation in difficult environments such as smoke from industrial chimneys.

Robustness reduces maintenance costs and increases the availability of boilers and equipment.

Extractive measurement consists of taking a gas flow from the chimney or the gas pipe via a sampling probe and conveying it to the gas analyzer.

The gas is sampled, treated in order to ensure optimal conditions for gas measurement.

Measurement of the concentration of 1 to 5 components

The Fuji Electric extractive multigas analyser range consists of non-dispersive 5-gas infrared analyzers. They allow simultaneous and continuous measurement by extraction of 1 to 5 gases from:

  • CO, CO2, NOx, SO2, CH4 and N2O by single or double beam NDIR technology
  • O2 by paramagnetic, Zirconia or electrochemical technology


  • Simple maintenance thanks to self-diagnostic functions
  • Good precision and excellent stability of the measurement over time
  • Large backlit display
  • Automatic zero and span calibration
  • Correction with oxygen
  • Modbus® protocol digital link
  • Large scale dynamics (1 to 20 configurable)

ZKJ – 5 components analyser – NDIR dual beam


Ideal for controlling polluting emissions

Uses a highly sensitive mass flow meter as a detector.

Simultaneous and continuous measurement of 5 gases :

CO2  –  CO  –  CH4  –  NOX  –  SO2  –  O2  –  NO  –  N2O


  • The reference cell of the double beam principle offers excellent performance
  • Low scales from 0-20 ppm
  • Excellent zero point stability: ± 1% FS per week
  • Integrated interference detectors help reduce cross interference optimally
  • Clean and intuitive interface with advanced diagnostic and calibration features

Measuring principle:

  • NOx, SO2, CO, CO2, CH4, NO: Non-dispersive infrared absorption method.
  • O2: Paramagnetic or electrochemical method (measuring element incorporated in the analyzer) or zirconia method (external analyzer type ZFK7)

ZRE – 5 components analyser – NDIR single beam


Compact and easy to use

  • Excellent stability over time
  • No influence of humidity on the measurement
  • Automatic calibration, communication and alarms

Simultaneous and continuous measurement of the concentration of 5 gases:

CO – CO2 – NO – NOX – SO2 – CH4 – O2


  • Simultaneous and continuous measurement of one to five components
  • Possibility for the user to select two scopes for each component and to modify them freely
  • Simple internal structure for easy maintenance
  • Compact and lightweight: 483 (W) × 133 (H) × 418 (D) mm, 8 kg
  • Complete range of O2 measurement technologies: electrochemical, paramagnetic or zirconia

Measuring principle:

The amount of infrared radiation absorbed in the measuring cell is detected with a micro mass flowmeter. The low impedance micro mass flowmeter has excellent interference immunity, and the sensor, without moving part, is insensitive to vibrations.
