Oxygen Analyzers for Multiple Industries

Oxygen analyzers have a wide range of applications across various industries. Their primary function is to measure the concentration of oxygen in gases or the surrounding atmosphere. This data is then used for various purposes, including:

  • Safety: One of the most critical applications is ensuring safety in environments with potential hazards. Oxygen analyzers are used in:
    • Industrial processes: They help monitor oxygen levels to prevent explosions in situations involving flammable materials. For instance, they are used in chemical plants, refineries, and facilities handling combustible materials.
    • Inert gas systems: These analyzers ensure that inert gases used to displace oxygen in enclosed spaces, like cargo tanks in ships, truly have low oxygen content to prevent explosions.
    • Confined spaces: Before personnel enter confined spaces for maintenance or repairs, oxygen analyzers are used to verify safe oxygen levels for breathing.
  • Process optimization: In various industries, precise oxygen control is crucial for efficient operation. Analyzers are used in:
    • Combustion processes: They help optimize fuel-to-air ratios in boilers and furnaces by measuring exhaust gas oxygen content. This improves efficiency and reduces energy waste.
    • Modified atmosphere packaging (MAP): Food and beverage manufacturers use oxygen analyzers to control oxygen levels in packaging to extend shelf life and preserve product quality.
  • Other applications: Oxygen analyzers also find use in:
    • Medical field: They are used to analyze respiratory gas mixtures and oxygen levels in breathing apparatuses.
    • Landfill gas management: These analyzers monitor oxygen levels in landfill gas to ensure proper functioning of methane capture systems.
    • Environmental monitoring: They are used to measure dissolved oxygen levels in bodies of water for pollution control and assessing aquatic health.

Inert Gas System (IGS)
Since oxygen is very reactive and can cause problems, it's crucial to closely monitor inert gases for even the smallest amounts of oxygen contamination. This ensures the gas meets the required quality standards.

Working principle of Oxygen Analyser

There are several types of oxygen analyzers, each employing a different principle to measure oxygen concentration.

Electrochemical Cell:

  • This type functions similarly to a miniature fuel cell.
  • The analyzer draws in a sample gas containing oxygen.
  • Oxygen diffuses through a special membrane (electrolyte) and reacts with electrodes within the cell.
  • This reaction generates a small electrical current proportional to the oxygen concentration.
  • The analyzer measures this current and converts it to an oxygen level reading (percentage or ppm).

Paramagnetic Sensor:

  • This method utilizes the magnetic properties of oxygen molecules.
  • Oxygen is attracted to strong magnetic fields, unlike most other gases.
  • The analyzer has a chamber containing small, nitrogen-filled spheres suspended within a powerful magnet.
  • When oxygen is present in the sample gas drawn into the chamber, it’s attracted to the magnetic field, causing the spheres to move slightly.
  • The degree of movement is proportional to the oxygen concentration. Sensors detect this movement and convert it to an oxygen level reading.


Zirconia Oxide Sensor: Utilizes a ceramic material that allows oxygen ions to pass through, creating a voltage related to oxygen concentration.

Tunable Diode Laser (TDL) Absorption Spectroscopy: Measures the amount of infrared light absorbed by oxygen molecules in the sample gas.

The choice of analyzer type depends on factors like desired accuracy, response time, and the presence of interfering gases.
